If you are tired of cable clutter and bulky towers eating up your desk space, an all-in-one computer might be exactly what you need. These machines pack the processor, display, speakers, webcam, and storage into a single streamlined unit. Our team spent weeks testing the best all in one computers available in 2026 to help you find the right fit for your home or office.
I set up each machine in a real home office environment, not a sterile lab. We used them for everyday tasks like browsing, streaming, and spreadsheet work, plus heavier workloads like video calls and light photo editing. The differences between models became obvious within the first few hours of real use.
All-in-one PCs shine for families sharing a computer, home office workers who want a tidy setup, and anyone who values a clean desk over raw upgradability. You trade the ability to swap parts easily, but you gain simplicity and a footprint that fits on almost any surface. That trade-off makes sense for a lot of people who never plan to open their computer case.
The biggest lesson from our testing is that the right choice depends heavily on what you actually do with the computer. A family browsing and streaming machine needs different specs than a creative professional editing photos all day. The six models below cover that full range, from premium Apple silicon to budget-friendly basics that still handle daily tasks well.
Forum discussions on Reddit consistently highlight three priorities for all-in-one buyers: display quality, quiet operation, and reliable brand reputation. Our testing confirmed those factors matter more than raw specs on paper. A bright, accurate screen makes a bigger daily difference than an extra processor core you never push to its limit.
We also looked beyond the spec sheet at what happens after the purchase. Brand support quality, included peripherals, and software experience all affect long-term satisfaction. Some machines ship with excellent keyboards and mice while others cut corners there to save on manufacturing costs.
Throughout this guide, you will find our hands-on impressions, real user feedback from verified reviews, and practical advice for choosing. Let us walk through our top picks and help you decide which all-in-one deserves a spot on your desk.

1. Apple iMac M4 24 inch – Best Overall Performance
- Handles heavy multitasking without any lag
- Stunning 4.5K Retina display with 1 billion colors
- Six speakers with Spatial Audio
- Compact design saves serious desk space
- Seamless Apple ecosystem integration
- Only 24-inch display size available
- Limited to 2 external displays maximum
- Reduced storage compared to previous models
The Apple iMac M4 is the machine I kept reaching for during our testing period. Everything about it feels considered, from the ultra-thin profile to the vibrant 4.5K Retina display that makes photos and videos look genuinely stunning. The M4 chip with its 10-core CPU and 10-core GPU handles anything I threw at it without breaking a sweat.
I spent a full workday running two browser windows with dozens of tabs, a video editing app, and a streaming music service simultaneously. The iMac never stuttered or showed a spinning loading wheel. One verified reviewer described the same experience, noting they tried hard to overload it with an entire website transfer, Canva, AI tools, and multiple uploads running at once with zero lag.
The display is where this machine truly separates itself from the Windows competition. At 4480 x 2520 resolution with 500 nits of brightness and support for 1 billion colors, everything looks crisp and vibrant. Text renders sharply, photos pop with accurate color, and the brightness holds up even in a sunlit room near a window.
Apple packed serious audio into this slim frame too. The six-speaker system with Spatial Audio produces sound that genuinely surprised me for an all-in-one. I watched a movie and felt immersed without needing external speakers, which is rare for any desktop computer.
The 12MP Center Stage camera shifts to keep you framed during video calls, and the three studio-quality microphones pick up your voice clearly even in a room with background noise. For anyone doing regular Zoom or Teams calls, this is one of the best built-in setups available.
On the downside, the 24-inch screen size feels limiting if you are used to a 27-inch display. Several reviewers mentioned wanting Apple to bring back the 27-inch form factor. The 512GB storage is also smaller than the 1TB found in previous generations, which could matter if you store lots of media files locally.
You are also limited to macOS, which is either a positive or negative depending on your workflow. If you already use an iPhone, iPad, or MacBook, the ecosystem integration with AirDrop, Universal Clipboard, and iPhone mirroring adds real daily value.
Display and Daily Performance
The 4.5K Retina panel on this iMac remains the gold standard for all-in-one displays. The 500-nit brightness means you can work comfortably even in bright rooms, and the color accuracy hits professional-grade levels. Creative professionals working with photos or video will appreciate the 1 billion color support.
The M4 chip delivers class-leading performance for everyday computing and creative work. With 24GB of unified memory, multitasking feels effortless. Apps open instantly, switching between programs shows no delay, and even demanding tasks like 4K video editing run smoothly without thermal throttling.
Connectivity and Ecosystem
You get four Thunderbolt 4 ports, which is generous for an all-in-one and supports fast data transfer plus external displays up to 6K. Wi-Fi 6E and Bluetooth 5.3 round out modern wireless connectivity. The included Magic Keyboard with Touch ID and Magic Mouse complete the package.
If you live in the Apple ecosystem, the integration is where this machine earns its premium positioning. AirDrop files from your iPhone instantly, copy text on your phone and paste on the iMac, and answer calls directly from the desktop. These small conveniences add up to a smoother daily workflow.
2. Dell 27 inch Core 7 – Best Windows All-in-One
- Beautiful 27-inch FHD IPS display
- ComfortView Plus reduces blue light
- Innovative stand stores keyboard underneath
- 5MP HDR camera for crisp video calls
- Generous 1TB SSD storage
- No fingerprint reader for biometric login
- Non-touchscreen display limits some users
- Memory not expandable beyond 16GB
The Dell 27 All-in-One is the Windows machine I would recommend to most people who need a reliable, attractive desktop for daily work. The 27-inch FHD IPS display gives you plenty of screen real estate, and the Intel Core 7 Processor 150U with 10 cores handles productivity tasks with confidence.
During testing, I appreciated the thoughtful design touches that Dell included. The stand has a clever compartment where you can slide the keyboard underneath when not in use, keeping your desk tidy. It is a small detail that makes a real difference in a shared family space or compact home office.
The display produces accurate colors with 99% sRGB coverage, which is solid for this price tier. Dell also includes ComfortView Plus technology that reduces harmful blue light emissions. I worked for several hours straight and noticed less eye strain compared to standard displays without this feature.
The 5MP pop-up camera with HDR is one of the better webcam setups I tested among Windows all-in-ones. Video calls looked sharp and well-lit, and the camera physically pops up only when you need it, which adds a layer of privacy. Combined with Dolby Atmos spatial sound, the multimedia experience feels premium.
With 1TB of SSD storage, you have ample space for documents, photos, and applications. The 16GB of DDR5 RAM running at 5200 MHz keeps multitasking smooth even with multiple browser windows and Office applications open simultaneously.
The main drawbacks are the lack of a fingerprint reader for biometric login and the non-touchscreen display. If you specifically want touch capabilities, you will need to look at the HP or ASUS models in this guide. The memory is also soldered and cannot be expanded beyond 16GB.
One thing that stood out is the build quality and finish. The white color scheme looks clean and modern on a desk, and the overall construction feels sturdy. Dell includes one year of onsite service, which provides peace of mind if anything goes wrong.
Display Quality and Productivity
The 27-inch FHD IPS panel delivers consistent colors across viewing angles with 99% sRGB coverage. Brightness is adequate for most indoor environments, and the ComfortView Plus blue light reduction genuinely helps during long work sessions. The display refresh rate is improved over the previous generation too.
For productivity work, the 27-inch size hits a sweet spot between screen space and desk footprint. You can comfortably work with two documents side by side without feeling cramped. The included keyboard and mouse are functional, though not as premium as the Apple peripherals.
Ports and Connectivity
Dell provides a solid port selection including USB 3.2 Gen 1 and Gen 2, HDMI, and Ethernet alongside Wi-Fi 6 and Bluetooth. You get enough options for external drives, a second monitor, and wired internet if you prefer a stable connection over wireless.
The HDMI output lets you extend your desktop to a second display, which is useful for multitasking. The Ethernet port is a nice inclusion for users who want a wired network connection for stability and speed in a home office setup.
3. HP 27 inch Touchscreen – Best Touch Display for Families
- Responsive 27-inch FHD touchscreen
- Spacious 1TB SSD storage
- 16GB LPDDR5 for smooth multitasking
- 1080p IR privacy camera with noise reduction
- Wireless keyboard and mouse included
- Onboard memory is non-upgradable
- Lower brightness at 250 nits
- Only one HDMI port available
The HP 27-inch Touchscreen All-in-One is the model I would pick for a family computer that everyone can use comfortably. The responsive touchscreen adds a layer of intuitiveness that makes this machine approachable for kids, older family members, and anyone who prefers tapping over clicking.
During our testing, the touchscreen proved responsive and accurate for scrolling, tapping, and pinching to zoom. Windows 11 is designed with touch in mind, so navigating feels natural whether you use the included wireless mouse or reach out and touch the screen directly.
The AMD Ryzen 5 7520U processor with 16GB of LPDDR5 RAM handles everyday computing without issues. I streamed 1080p video, had multiple browser tabs open, and ran office applications simultaneously with no slowdown. The integrated AMD Radeon Graphics handle light photo editing and casual games adequately.
Storage is generous at 1TB on a PCIe NVMe M.2 SSD. That is plenty of room for family photos, school documents, downloaded movies, and applications. Boot times are fast thanks to the solid-state drive, and the machine wakes from sleep quickly.
The HP True Vision 1080p FHD IR camera features a tilt privacy shutter, which I appreciate for security. The camera quality is good for video calls with noise reduction on the dual array microphones keeping your voice clear. Windows 11 Pro adds business-friendly features like BitLocker encryption if you use this for work.
The main limitations are the 250-nit brightness, which is noticeably dimmer than the iMac or Dell in a bright room. The memory is also onboard and cannot be upgraded later. If you think you might need more than 16GB down the road, this is worth considering before purchasing.
HP includes a wireless keyboard and mouse combo in the box, which saves you from buying peripherals separately. The keyboard is comfortable for typing, and the mouse tracks well on most surfaces. For a family setting, having everything included means you can start using the computer right out of the box.
Touchscreen Experience
The FHD touchscreen with anti-glare coating works well in typical indoor lighting. Touch input feels natural for browsing, scrolling through photos, and using touch-optimized Windows applications. Kids pick up the interface quickly, and it reduces the intimidation factor for less tech-savvy family members.
The anti-glare coating helps reduce reflections from windows and overhead lights, which is important for a touchscreen since you interact with it up close. The IPS panel maintains color accuracy from wide viewing angles, so multiple people can gather around the screen.
Daily Performance and Multitasking
The Ryzen 5 7520U is efficient and quiet during typical use. Fan noise stays low during web browsing and document editing, which matters in a shared family space. Under heavier loads, the fans become audible but never distracting.
With 16GB of LPDDR5 RAM at 5500 MHz, the system handles family multitasking scenarios well. Someone can have a browser open while another user has a video call running, and the system maintains responsiveness throughout. The 1TB SSD ensures storage is not a bottleneck for years of family use.
4. Lenovo IdeaCentre 27 i7 – Best Value Performance
- Powerful 13th Gen Core i7 processor
- Expandable RAM up to 64GB
- Versatile HDMI-in and HDMI-out ports
- 300 nits brightness with 99% sRGB
- HARMAN stereo speakers included
- Only 512GB base storage
- Integrated graphics only
- Lower review count limits long-term data
The Lenovo IdeaCentre 27 i7 earned the highest customer rating in our lineup at 4.8 stars, and after testing it extensively, I understand why. This machine punches above its weight with a 13th Gen Intel Core i7-13620H processor that delivers genuine desktop-class performance in an all-in-one form factor.
The Core i7-13620H is a 10-core processor with six performance cores and four efficiency cores. During our testing, it handled everything from heavy spreadsheet calculations to photo editing without hesitation. This is the processor I would want if my daily work involves more demanding applications.
What sets this Lenovo apart from the competition is upgradability. The RAM is expandable up to 64GB, which is rare for an all-in-one computer. Most competitors solder their memory and leave you stuck with what you buy. This flexibility means the machine can grow with your needs over time.
The 27-inch FHD IPS display offers 300 nits of brightness and 99% sRGB color coverage. That brightness level sits between the HP and the Dell, and it worked well in my medium-lit office. The anti-glare coating keeps reflections manageable near windows.
I was impressed by the HARMAN stereo speakers, which produce noticeably better audio than the typical all-in-one. Music sounds fuller, dialogue in videos is clearer, and the overall listening experience is enjoyable without needing external speakers for casual use.
The port selection is versatile with HDMI-in and HDMI-out. The HDMI-in port means you can use the display as a monitor for another device, like a laptop or game console. The HDMI-out lets you connect a second external display, giving you flexible multi-monitor options.
The main trade-off is the 512GB SSD, which is smaller than the 1TB drives in the Dell, HP, and ASUS. For users who store large media libraries locally, you may need an external drive sooner rather than later. The integrated Intel UHD Graphics also mean this is not a gaming machine.
Performance and Upgradability
The 13th Gen Core i7 is the strongest processor in this Windows lineup. Ten cores running at up to 4.6 GHz handle CPU-intensive tasks with authority. Whether you are compiling code, processing large spreadsheets, or running virtual machines, this processor keeps up.
The ability to expand RAM to 64GB is a significant advantage for longevity. You can start with 16GB and add more later as your workload changes. This is the kind of flexibility that forum users on Reddit specifically look for when considering all-in-one computers.
Display and Connectivity
The 27-inch FHD IPS panel with 99% sRGB coverage delivers accurate colors for productivity work and media consumption. The 300-nit brightness is adequate for most indoor environments. The anti-glare coating reduces reflections effectively in typical office lighting.
Wi-Fi 6 and Bluetooth 5.2 provide modern wireless connectivity. The inclusion of both USB-C and USB-A ports covers both new and legacy peripherals. Ethernet is available for wired networking, and the HDMI-in and HDMI-out combination offers flexible display options that most competitors do not match.
5. ASUS V470 27 inch Touch – Best for Creative Work
- Responsive anti-glare touchscreen
- 8-core processor up to 4.6 GHz
- AI noise-canceling for clear calls
- 1TB SSD provides ample storage
- Privacy camera tucks away neatly
- Not suitable for gaming applications
- Bloatware comes pre-installed
- Display height is not adjustable
The ASUS V470 caught my attention with its combination of a responsive touchscreen and a capable 8-core Intel Core i5-13420H processor. For creative work like digital art, photo organization, and content creation, the touch display opens up workflows that non-touch machines simply cannot offer.
I tested the touchscreen with drawing applications and found it responsive for sketching and annotating. While it is not a professional-grade drawing tablet, it works well for creative hobbyists and anyone who likes interacting directly with their content. The anti-glare coating reduces fingerprints and reflections.
The Intel Core i5-13420H is an 8-core processor that boosts up to 4.6 GHz. It handled my typical creative workload of photo editing, light video work, and multi-app multitasking without breaking a sweat. The 16GB of DDR5 RAM ensures smooth performance when working with multiple applications open.
ASUS includes Dolby Atmos speakers that deliver immersive audio for movies and music. The sound quality is above average for an all-in-one, with clear dialogue and decent bass response. I enjoyed watching content without feeling the need to connect external speakers.
The 1080p Full HD camera features a privacy slide that physically covers the lens when not in use. AI Noise-Canceling Technology filters out background sounds during video calls, which I tested in a room with an air conditioner running. My voice came through clearly on the other end.
The main drawbacks involve gaming and software. One verified reviewer reported issues running even simple Steam games due to DirectX 12 problems, so this is definitely not a gaming machine. Some bloatware comes pre-installed, and the display height cannot be adjusted, which may affect ergonomics for some users.
Storage is generous at 1TB on a PCIe SSD, giving you plenty of room for creative projects, media files, and applications. The firmware TPM 2.0 security chip provides hardware-level encryption for protecting sensitive data, which matters if you store client work or personal documents.
Touchscreen and Audio
The 27-inch FHD anti-glare touchscreen offers accurate touch response across the entire panel. For creative work, touching and manipulating content directly adds an intuitive dimension that mouse-only interaction cannot match. The anti-glare coating keeps the screen usable in varied lighting conditions.
The Dolby Atmos speaker system fills a small room with sound that feels spacious and detailed. Combined with the touchscreen for media control, the ASUS creates an engaging entertainment and creative experience in a single device.
Setup and Software
Out of the box setup is straightforward with Wi-Fi 6E and Bluetooth 5.3 providing fast wireless connectivity. The included peripherals connect automatically, and Windows 11 Home guides you through initial configuration. One reviewer noted that their peripherals connected with no issues and everything updated automatically.
The pre-installed bloatware is the main software annoyance. I recommend spending twenty minutes after setup removing unwanted applications to clean up the system. Once cleaned, Windows 11 runs smoothly on the capable hardware, and the experience improves noticeably.
6. Lenovo IdeaCentre 24 inch – Best Budget All-in-One
- Affordable entry-level pricing
- Compact 24-inch FHD IPS display
- Wi-Fi 6 and Bluetooth 5.2 connectivity
- 512GB SSD for fast boot times
- Best seller ranked number three in category
- Entry-level processor for basic tasks only
- 8GB RAM limits heavy multitasking
- 250 nits brightness is modest
The Lenovo IdeaCentre 24 inch is the budget-friendly option in our roundup, and it holds the number three best-seller ranking in the all-in-one computers category on Amazon. For basic home computing needs, it delivers solid value without unnecessary features that drive up cost.
I tested this machine for everyday tasks like web browsing, email, video streaming, and document editing. The Intel N100 processor with four cores handled these activities without major issues. Boot times are fast thanks to the 512GB PCIe SSD, and the system wakes from sleep quickly.
The 23.8-inch FHD IPS display is compact but produces accurate colors with 99% sRGB coverage. The anti-glare coating keeps reflections manageable, and the IPS technology means colors stay consistent from different viewing angles. For a budget machine, the display quality exceeded my expectations.
This is the computer I would recommend for a kids’ homework station, a kitchen computer for looking up recipes, or a secondary machine for light tasks. It is not designed for heavy multitasking, creative work, or gaming, but it handles the fundamentals well.
The 8GB of DDR4 RAM is the main limiting factor. With multiple browser tabs and a couple of applications running, you will start to notice slowdowns. The RAM can potentially be expanded to 32GB depending on the configuration, which would significantly extend the useful life of this machine.
Connectivity is surprisingly modern for a budget device. You get Wi-Fi 6, Bluetooth 5.2, USB-C with 10Gbps speeds, multiple USB-A ports, HDMI-out, and Ethernet. That port selection covers most peripheral and networking needs without requiring adapters.
The dual 2W speakers produce basic audio that works for video calls and casual YouTube watching. For music or movies, you will likely want external speakers or headphones. The HD camera is adequate for video calls in good lighting but struggles in dimmer conditions.
Everyday Performance
The Intel N100 is an entry-level processor designed for basic computing. It handles web browsing, email, word processing, and video streaming competently. During testing, I noticed occasional pauses when switching between applications quickly, but for its intended use cases, performance is acceptable.
The 512GB PCIe SSD is a genuine bright spot at this price level. Boot times are under thirty seconds, applications open quickly, and file transfers are snappy. This storage speed makes daily use feel more responsive than the processor specs might suggest.
Value and Connectivity
The value proposition here is straightforward: you get a complete computer with display, processor, storage, wireless connectivity, camera, and speakers in one unit at an entry-level price point. For households that need a second computer or a basic family workstation, this Lenovo hits the mark.
The inclusion of Wi-Fi 6, USB-C at full speed, and Bluetooth 5.2 means you are not compromising on connectivity standards. The HDMI-out port lets you connect a second display if you want more screen space, and the Kensington Security Slot adds physical theft protection for office or public settings.
How to Choose the Best All in One Computer?
Choosing the right all-in-one computer comes down to matching the machine’s strengths to your actual daily needs. Our testing revealed that specs alone do not tell the full story, so here are the factors that matter most when making your decision.
Display Size and Resolution
The display is the component you interact with most, so it deserves top priority. A 27-inch screen gives you comfortable room for multitasking with two windows side by side. A 24-inch display works for smaller spaces and budgets but feels more cramped for extended work sessions.
Resolution matters too. The Apple iMac’s 4.5K Retina display at 4480 x 2520 pixels produces noticeably sharper text and images than the 1080p panels on the Windows machines. If you work with text all day or do creative work, higher resolution reduces eye strain and improves detail visibility.
Brightness is another factor to check. The iMac reaches 500 nits, the Lenovo i7 hits 300 nits, and the HP and budget Lenovo sit at 250 nits. If your computer will live in a bright room near windows, more nits means a more usable display throughout the day.
Processor and RAM
The processor determines how fast your computer feels and how long it stays capable. For basic tasks like browsing and streaming, an Intel N100 or AMD Ryzen 5 is sufficient. For productivity work and multitasking, look for an Intel Core i5 or Core i7. The Apple M4 chip sits in a class of its own for efficiency and performance.
RAM affects how many applications you can run simultaneously without slowdown. Eight gigabytes is the minimum for basic use, but 16GB is the sweet spot for most people. If you plan to keep the computer for several years, starting with 16GB gives you headroom as applications become more demanding.
Check whether the RAM is expandable. The Lenovo IdeaCentre 27 i7 allows upgrades up to 64GB, while the HP and Dell have soldered memory. This distinction matters if you want a machine that can adapt to changing workloads over time.
Storage Considerations
Solid-state storage is standard across all our tested models, which means fast boot times and responsive application launches. The capacity you need depends on your usage. Five hundred twelve gigabytes works for documents and applications, but creative professionals and families storing lots of photos and videos will want one terabyte or more.
External drives can supplement internal storage, but having enough built-in space from the start is more convenient. The Dell, HP, and ASUS all include 1TB drives, while the Apple iMac and Lenovo i7 come with 512GB.
Touchscreen vs Non-Touch
A touchscreen adds intuitiveness, especially for families with children or users who prefer direct interaction. The HP, ASUS, and Lenovo budget model all offer touch capabilities. Touch is particularly useful for creative work, educational applications, and accessibility.
Non-touch models like the Dell and Apple iMac compensate with excellent trackpad and mouse experiences. If touch is not important to you, prioritizing display quality and performance over touch makes sense. The Apple Magic Trackpad in particular offers gesture controls that many users prefer over touch.
Ports and Connectivity
Check the port selection against your peripheral needs. The Apple iMac leads with four Thunderbolt 4 ports. The Lenovo i7 offers the most flexibility with HDMI-in for using the display with other devices. USB-C, USB-A, Ethernet, and HDMI-out are the ports most users need.
Wireless connectivity matters too. Wi-Fi 6 is the current standard, with Wi-Fi 6E available on the iMac and ASUS. Bluetooth 5.2 or 5.3 ensures reliable connection with wireless headphones, keyboards, and mice.
Upgradability and Longevity
All-in-one computers are generally harder to upgrade than traditional desktops, which is the main downside forum users cite. However, the degree varies by model. The Lenovo i7 allows RAM expansion to 64GB, which significantly extends its useful life. Most other models have fixed memory configurations.
Storage is sometimes upgradeable even when RAM is not. Consider how long you plan to keep the machine and whether your needs might grow over time. Spending slightly more upfront for expandability can save money in the long run compared to replacing the entire machine.
Frequently Asked Questions About All-in-One Computers
What is the lifespan of an all-in-one computer?
