The best all-in-one computers

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 on the market. The best all-in-one computer we've tested is the Asus Zen AiO Pro Z240IE, which packs a gorgeous 4K display and discrete graphics into a sleek design. 

If you're looking for something less expensive, our value pick is the Acer Aspire Z24, which offers a great all-in-one PC for under $1,000.

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).

And for a sneak peek at the newest  systems, check out recent stories, like our first glimpse of a new Apple iMac design.
