The best all-in-one computers give you the power you need without a lot of tower or cable clutter. We tested over a dozen all-in-one computers (both Windows PCs 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 looking for a great home computer - they take up less space than traditional towers and offer more screen space than even the largest laptops. These unique systems pack their components, ports, and monitors into one unit, making them easy to place on your desk, plug in, and take to work (or play).

The all-in-one computers we review are often best suited for specific applications like photo and video editing or tasks that require professionalism, but the more affordable units are great all-around performers, providing something for every member of the family, whether it's kids doing schoolwork or parents trying to get some work done or organize a family photo album. Whatever you want out of a desktop computer, one of the best all-in-one computers is up to the task.

What are the best all-in-one computers?

The best all-in-one PC we tested is the Asus Zen AiO Pro Z240IE, which combines a sleek design with a gorgeous 4K display and discrete graphics card. It's also packed with features like high-speed USB-C connectivity and an HDMI input, allowing you to use it as a monitor long after you've bought another PC.

If you're looking for something cheaper, our pick is the Acer Aspire Z24, which offers a great all-in-one PC for under $1,000. In addition to its affordable price, this sleek all-in-one PC comes with a six-core Intel Core i7 processor that provides plenty of power for everything from household to professional tasks.

The updated Apple iMac with 5K Retina Display (27-inch) is still the best all-in-one computer for photo and video editing, and a fantastic all-around system, thanks to the classic iMac design and new hardware that boosts the performance of the CPU and GPU, providing excellent power for all your tasks. It's especially good for photo and video editing, but the Apple iMac will work just as well in any home or office.

The best all-in-one computer for artists, however, there's nothing better than the Microsoft Surface Studio 2, which gives users a spacious touchscreen with best-in-class pen support, all laid out for optimal comfort. The hinged screen drops down at a low angle, mimicking the tilt of an artist's drafting table and pairing it with great processing and graphics hardware.

For unparalleled power, just look at the Apple iMac Pro, which is the ultimate all-in-one computer workstation for professionals. High-end processors and ISV-certified graphics are paired with fast storage and up to 128GB of memory for a non-stop combination of power and capability.
