The best all-in-one (AIO) PCs are perfect for those who want a fuss-free computing experience. While traditional desktop computers often involve multiple peripheral components (e.g. monitor, keyboard, and mouse) connected to a bulky tower unit by numerous tangled cables, all-in-one setups are usually simpler and much more streamlined. Our product experts tested and reviewed some of the top AIO models from popular manufacturers including Apple, Microsoft, and Lenovo to find the best ones on the market.

Straddling the line between desktops and laptops, all-in-one computers combine the top features (e.g. portability, large screens) offered by both of these form factors into a sleek and stylish personal computing device. These PCs do away with unwieldy tower cases by placing all the internal hardware components (e.g. CPU, motherboard, and speakers) behind the display itself, integrating everything into a single chassis.

And since most of them also come with wireless keyboards and mice, the clutter of jumbled wires is eliminated from the picture. The majority of AIO computers offer different pre-built configurations, but many allow users to upgrade hardware such as RAM and SSDs as well.

Premium all-in-one PCs like Apple's Retina 5K iMac feature large, professional-grade displays that make them ideal for high-accuracy tasks such as photo editing. Some others, like Microsoft's Surface Studio 2, even have stylus support that allows them to be used for creative tasks like digital illustrations. Many AIOs also include handy additions like built-in wireless charging pads and privacy-oriented webcams that retract inside the case when not being used.

Here are our top picks for the best all-in-one PCs currently available in the market.

Best Overall: Apple 27-inch iMac with Retina 5K Display (2020)

What We Like
  • Color-accurate 5K resolution display

  • Extensive hardware configuration options

What We Don't Like
  • No Wi-Fi 6 support

Powerful and versatile in equal measure, Apple's iMac is one of the best all-in-one PCs out there. Its 27-inch Retina 5K display comes with a resolution of 5120 x 2880 pixels, giving you lots of visual real estate for both work (e.g. multitasking with several programs) and play (e.g. watching streaming 4K videos). The panel also supports P3 wide color space and True Tone technology that make it ideal for specialized workflows like photo and video editing, where color accuracy is of utmost importance.

It's true that the newest iMac (with Apple's M1 SoC) features a more modern design and a slimmer profile, along with goodies such as a six-speaker system and Touch ID sensor. However, this 2020 model more than makes up for it by offering a much wider range of hardware configurations, having (up to) a tenth-generation Intel Core i9 CPU, 128GB of RAM, and 8TB of SSD storage. This lets you choose the best configuration according to your usage requirements, while leaving room for future upgrades.

For fast internet connectivity and easy wireless pairing with a diverse array of peripherals (e.g. keyboards, headsets), the iMac includes Wi-Fi 802.11ac, Gigabit Ethernet, and Bluetooth 5.0. Among other I/O options are USB Type-A, 3.5mm audio, Thunderbolt 3 (with support for up to two 6K displays for multi-monitor configurations), and an SDXC card slot. The Apple iMac also sports a 1080p FHD webcam and a three-mic array for high-quality video calls, which have become even more essential in today's work-from-home world.

CPU: 10th Generation 8-Core Intel i5, 8-Core Intel i7, 10-core Intel i9 | GPU: AMD Radeon Pro 5300 or AMD Radeon Pro 5500 XT | RAM: Up to 128GB DDR5 | Storage: Up to 8TB SSD

Best Touchscreen: Lenovo Yoga A940

Lenovo Yoga A940-27ICB
What We Like
  • Customizable precision control dial

  • Integrated wireless charging pad

What We Don't Like
  • Included stylus isn't exactly the best

If you're looking for a feature-laden all-in-one PC that can also double up as a tablet, we suggest checking out Lenovo's Yoga A940. Sporting a resolution of 3840 x 2160 pixels, its 27-inch touchscreen display offers a convenient way of interacting with on-screen elements. The 4K panel is mounted on a hinge that can tilt forward up to 25 degrees, thus making it easier to rest your hand when using the bundled stylus to create digital illustrations or jot down notes.

Measuring 25 x 18.3 x 9.6 inches in size, the Yoga A940 boasts a well-built (albeit plastic) chassis, with thoughtful additions like a wireless charging pad and storage space(s) for the keyboard and mouse integrated into the base. Our recommended configuration includes Intel's eighth-generation Core i7 processor, 16GB RAM, a 256GB SSD, and a 1TB HDD.

You also get AMD's Radeon RX 560 GPU (with 4GB discrete graphics memory) for resource-heavy work. During our reviewer's testing of the machine, these specs resulted in PCMark scores of 5226 (for productivity tasks) and 7635 (for video editing), both well above the minimum threshold.

For wireless pairing and internet connectivity, Lenovo Yoga A940 features Bluetooth 4.2, Wi-Fi 802.11ac, and Ethernet. You also get all essential I/O options including HDMI, USB Type-A and Type-C (with Thunderbolt), 3.5mm audio, and a multi-format card reader. The Yoga A940's 1080p FHD webcam supports Windows Hello for secure authentication, although our product tester found it to be just OK for video calls.

Best for Business: Acer Aspire C27 AIO

What We Like
  • Great overall performance

  • Sliding webcam shutter for privacy

What We Don't Like
  • No USB Type-C port(s)

Offering a bevy of practical features in a smartly designed body, Acer's Aspire C27 is an all-in-one PC you (and your business) can rely on. Its 27-inch display boasts a resolution of 1920 x 1080 pixels, and can be tilted both forward (up to 25 degrees) and backward (up to 5 degrees) for an optimal viewing experience. The FHD panel comes with a matte, non-reflective finish that helps in reducing eye strain caused by extended hours of usage.

Talking about hardware, our recommended build of the Aspire C27 packs in a tenth-generation Intel Core i5 CPU, alongside 12GB of RAM and 512GB of SSD storage. Also included in the mix is NVIDIA's GeForce MX130 GPU, with 2GB of dedicated graphics memory.

Our reviewer's testing of this configuration yielded PCMark scores of 3265 (overall) and 2879 (photo editing). And even though these are fairly modest numbers, there's no doubting the fact that the all-in-one is more than capable of handling day-to-day productivity workflows, involving everything from email to office applications.

The Aspire C27 includes Wi-Fi 802.11ac, Gigabit Ethernet, and Bluetooth 5.0 for internet and wireless multi-peripheral connectivity. There's USB Type-A, HDMI, and 3.5mm audio ports for I/O, but unfortunately no USB Type-C port(s). The integrated 720p webcam works well and even gets a  sliding shutter for increased privacy, but our product tester found its video quality to be a bit underwhelming. Among other notable additions are stereo speakers, and bundled wireless keyboard and mouse that ensure you have a complete system out of the box.

  • Expensive

Loaded to the gills with powerhouse features, HP's Envy 32 is a premium all-in-one PC that makes its sky-high asking price almost seem justified. Its 32-inch display has a resolution of 3840 x 2160 pixels, and comes with an anti-reflective coating that helps in alleviating eye fatigue by reducing glare. The 4K panel is also ideal for high-accuracy workflows like photo editing, thanks to a peak brightness of 600 nits and 98 percent coverage of the DCI-P3 color gamut. These numbers put it on par with some of the best all-in-one displays out there, such as that of Apple's 27-inch iMac.

The Envy 32 is powered by a ninth-generation Intel Core i7 CPU, working in tandem with 32GB of RAM and 1TB of SSD storage.

HP Envy 32 also includes HDMI, USB (both Type-A and Type-C, with Thunderbolt 3), 3.5mm combo audio, and a 3-in-1 card reader slot as major I/O options. A 5MP webcam also comes built-in, complete with support for Windows Hello biometric authentication.

CPU: Intel Core i7 (9th generation) | GPU: Nvidia GeForce RTX 2060 | RAM: 16/32GB DDR4 | Storage: 1TB SSD

Best for Creative Professionals: Microsoft Surface Studio 2

What We Like
  • Tilting color-calibrated display

  • Surface Pen works great

What We Don't Like
  • Outdated hardware specifications

If you're a creative professional who designs 3D illustrations and digital artworks for a living, Microsoft's Surface Studio 2 might just be the perfect all-in-one PC for you. It features a 28-inch PixelSense display with a resolution of 4500 x 3000 pixels, with full support for both sRGB and DCI-P3 color spaces.

Each panel is individually color-calibrated for improved accuracy, and the unique design of the Zero Gravity hinge allows it to be tilted into drawing position with just one finger. According to our product tester, the touchscreen is as responsive as actual paper when it comes to working on it with the Surface Pen.

With the top configuration having Intel's seventh-generation Core i7 processor, 32GB RAM, a 2TB SSD, and NVIDIA's GeForce GTX 1070 GPU (with 8GB dedicated graphics memory), there's no doubting that the Surface Studio 2 is a powerful machine that can power through anything you throw at it.

Our reviewer's testing also yielded PCMark scores of 4541 (productivity) and 3554 (digital content creation), which are admirable. But as good as it is, the hardware of this all-in-one PC is severely outdated by today's standards.

There's Wi-Fi 802.11ac, Bluetooth 4.2, and Gigabit Ethernet included for handling network and wireless connectivity. You also get a decent (albeit limited) choice of I/O options, with USB (both Type-A and Type-C), 3.5mm audio, and a full-size card reader slot included.

On the plus side, you get a 5MP webcam and dual microphones for high-quality 1080p FHD video calls. Some other noteworthy features include an integrated TPM 2.0 chip (for hardware-based enterprise-grade security), and Surface Dial support which allows on-screen elements such as menus to be configured more precisely.

CPU: Intel Core i7 (7th generation) | GPU: Nvidia GeForce GTX 1070 | RAM: Up to 64GB DDR4 | Storage: Up to 2TB SSD

Best Budget: HP 22-inch All-in-One Desktop Computer

What We Like
  • Built-in DVD writer

  • Affordable price

What We Don't Like
  • Can't handle resource-intensive tasks

Having the right balance of features and performance, HP's 22 Series belies its humble price tag. Its 21.5-inch display comes with a resolution of 1920 x 1080 pixels, and is perfect for things like web browsing and streaming video content. The FHD panel also tilts forward (up to 20 degrees) and backward (up to 5 degrees) for easy adjustment of the viewing angle, and is bordered by thin bezels that help in reducing the machine's overall physical footprint.

The 22 Series is powered by an AMD Athlon Silver 3050U CPU, alongside 4GB of RAM and 256GB of SSD storage. While this hardware is pretty basic, it is capable of handling everyday computing workflows such as office documents and (some) multitasking. That said, we recommend upgrading the RAM (expandable up to 16GB) for better overall performance. You also get an integrated pop-up webcam and dual microphones for video calls.

HP 22 Series includes Wi-Fi 802.11a/b/g/n, Ethernet, and Bluetooth 4.2 for internet connectivity and wireless pairing with peripherals like keyboards, mice, and headphones. In terms of I/O options, you get all standard ports such as HDMI, USB Type-A, 3.5mm combo audio, as well as a 3-in-1 card reader slot.

However, what's particularly interesting is the integrated side-mounted DVD writer, which is something of a rarity these days, even in all-in-one PCs that are much more expensive. Measuring 19.3 x 8 x 14.9 inches and weighing around 12.5 pounds, the 22 Series is fairly compact and lightweight, which allows for easier portability. It also comes bundled with a wired mouse and a keyboard.

CPU: Intel Core i7 (10th generation) | GPU: Intel UHD Graphics 630 | RAM: Up to 32GB | Storage: 1TB M.2 SSD

Best AMD: HP 27-inch Flagship All-in-One Desktop Computer (2020)

What We Like
  • Great overclocking potential

  • Side-mounted USB port for easier access

What We Don't Like
  • No wireless keyboard or mouse

Ever since their introduction a few years ago, AMD's Ryzen series of processors have been consistently hitting it out of the park in terms of overall performance (and everything else). If that's something you want, we suggest taking a look at HP's all-in-one PC. Boasting a resolution of 1920 x 1080 pixels, its 27-inch FHD display is bordered by thin side bezels that maximize the viewing area, while keeping the computer's overall design fairly minimal. You also get ten-point multitouch input for interacting with on-screen elements conveniently.

Powered by an AMD Ryzen 5 4500U CPU, our recommended configuration also packs in 32GB of RAM and 1TB of SSD storage. While this hardware is powerful enough to tackle everything from photo/video editing to 4K video streaming, the processor makes things even better. The CPU has a base frequency of 2.3GHz but can be overclocked up to 4.0GHz, which allows it to handle resource-intensive tasks like 3D rendering and (some) gaming.

Then there are HP's usual additions like the 1080p FHD pop-up webcam (which retracts inside the top bezel when not in use for enhanced privacy) and front-facing speakers, which make this 2020 model a great everyday computer for everyone from students to home professionals.

There's Wi-Fi 802.11ac, Ethernet, and Bluetooth 4.2 for internet and wireless connectivity, and the all-in-one includes HDMI, USB Type-A, 3.5mm combo audio, as well as a 3-in-1 card reader slot as primary I/O options. Also bundled with the package are a wired keyboard and mouse.

CPU: AMD Ryzen 5 4500U | GPU: Integrated AMD Radeon | RAM: Up to 32GB | Storage: Up to 1TB SSD

Final Verdict

Having features like a high-resolution display, top-tier hardware, and lots of connectivity options, Apple's 27-inch iMac (view at Amazon) is our top choice as the best all-in-one PC currently available. Its Retina 5K panel renders everything from 4K videos to large digital illustrations with exceptional detail, and the ability to connect two 6K external monitors allows for a variety of powerful multi-monitor setups. You also have a wide range of options to pick from when it comes to hardware configurations.

If you'd rather have something similar with Windows 10 as the platform of choice, we suggest Microsoft's Surface Studio 2 (view at Amazon) With a large, color-calibrated display that can be tilted with just one finger and features enhanced stylus support, the AIO computer is the best tool for digital creativity. The hardware specifications are also quite capable (even if outdated) for handling all kinds of resource-intensive tasks.

FAQs

What is an all-in-one PC?
An all-in-one (AIO) PC is a computer where the monitor and tower are in the same unit. This means that the monitor houses the motherboard, RAM, and other components that make the computer, well, a computer. This design concept helps to save space, which is perfect for homes and offices that are on the smaller side.

Can you use an all-in-one PC as a monitor for another computer?
Short Answer: No

Long Answer: Unfortunately, no. All of the HDMI, USB-C, or DisplayPort connections on an AIO computer are display OUT, not display IN. This means that you can connect it to another monitor for a multi-screen setup, but you cannot use it as a secondary monitor for another system.

Can users upgrade all-in-one PCs?
It depends on the computer. Some AIOs are user-upgradeable while others, like the Apple iMac, feature integrated components that cannot be removed. Integrated components mean that if something fails, like a hard drive or power supply, you have to ship the whole thing back to the manufacturer for repair. It's oftentimes much cheaper to just buy a new AIO than repair an integrated part. Even if you're able to upgrade components yourself, you'll have to make sure that the new ones are made to fit into an AIO. Read your AIO's operating manual carefully to make sure you're buying the correct components and follow instructions exactly when removing and adding parts.

What to Look for When Buying AIOs

Screen Size

Of course, the primary focus of an AIO PC is the screen. It's the one component you definitely will not be able to upgrade, so it's important that you get one that will do everything you need. Generally larger numbers are getting in this case.

Specifications

AIO PCs can be hard to upgrade down the line, so it's even more important to pay close attention to what your PC offers out of the box. Things to pay attention to include the processor, RAM, storage, graphics card (if applicable) and the screen size.

Included Accessories

Some AIO PCs come with extras, like a mouse, keyboard, or even a stylus. Look for an AIO PC that comes with some bonuses that make owning it a little more fun. An amazing sound system or wireless charging pad come to mind.
