The best all-in-one computers combine a PC and monitor to give you the desktop power you need without the bulk of a tower or a tangle of cables. We've tested more than a dozen all-in-one desktops (both Windows machines and Apple iMacs) to find the best desktop and monitor combinations you can buy.
All-in-one desktops are a great middle ground for those seeking a great home computer — they take up less room than traditional towers, and offer more screen space than even the largest laptops. These unique systems pack their components, ports and monitors into a single unit, allowing you to easily put one on your desk, plug in and get to work (or play).

It's especially well-suited to photo and video editing, but the Apple iMac will fit just as well in any home or office.
For the very best all-in-one computer for artists, however, there's no beating the Microsoft Surface Studio 2, which gives users a spacious touchscreen with best-in-class pen support, all positioned for optimal comfort.

With a powerful 7th-gen Intel Core i7 processor, the iMac embarrassed the competition in our benchmark tests, putting up some of the best scores this side of the iMac Pro.

How to choose the best all-in-one computer for you
When shopping for a new desktop like one of the best all-in-one computers listed above, it helps to have a clear idea of what your intended uses are for the new system. If you're after a basic machine for web browsing, there are plenty of budget systems that will fit the bill, but more demanding uses like editing photo and video or even creating new artistic content will demand a more powerful system.
For most users, we recommend looking for something with a Core i5 processor or better, with at least 8GB of memory, but more demanding users will want to opt for something more powerful, like an Intel Core i7, and more RAM will translate into faster, smoother operations. You may also want a discrete graphics card if you want to do any sort of gaming or media work.
Storage is also a major consideration. While many of the systems on our list offer 1TB or more of storage, we find that the best option is a dual drive system that offers a larger hard drive for file storage and a faster SSD for storing the operating system and programs.
Touch capability is common on many all-in-one computers, but not on Apple's iMac. If you want touch or stylus support, you'll definitely want to get a Windows machine.
And don't forget about the display. Larger screens are great, but you may get better bang for your buck by focusing on resolution, with 4K displays becoming more common, and some high-end all-in-ones offering even higher resolution options.
How we test all-in-one PCs
Every all-in-one we review goes through a variety of benchmark tests in Purch Labs as well as long hours of real-world use. As with our laptop reviews, we use a colorimeter to measure the brightness, color accuracy and color gamut of each all-in-one's display.
For performance, we use the Geekbench 4 test to measure a system's overall processing abilities. We also run a custom spreadsheet test to see how long a PC takes to match thousands of names to addresses. To evaluate each system's hard drive speed, we measure how long it takes to copy 4.97 worth of files.
If an all-in-one has discrete graphics, we run it through many of the same benchmarks we use for gaming PCs. That includes 3DMark Fire Strike, as well as the built-in benchmark tools of games like Rise of the Tomb Raider, Hitman and Grand Theft Auto V. If an all-in-one is made to support virtual reality, we'll also run the SteamVR Performance Test.
Most importantly, we spend a ton of time simply using each all-in-one desktop for everyday activities. We watch movies, do work, play games, and blast music on the speakers, all to get a better sense of which ones are worth your money.
What do all-in-one computers cost?
All-in-One computers run the gamut from affordable to premium pricing. Budget-friendly systems can be found for less than $1000, but will generally be limited to full HD resolution displays and low-powered Celeron and Pentium processors. The best all-in-one desktops can cost $2,000 or more, and boast 4K displays, the latest Intel Core i7 processors and discrete graphics cards from Nvidia and AMD.
Since these units are always plugged in, you might want to also invest in a good surge protector to make sure your all-in-one stays in good shape.
