All-in-one computers have become very popular as everything you’d normally find in a desktop is combined in one unit. Instead of needing separate units -- the display monitor and the computer tower, you’re provided with a sleek design that has all the same functions that a traditional desktop has while saving on space.

Another reason to consider getting an all-in-one desktop computer is that it also comes with upgrades you’d normally get only as add-ons. The archaic computer tower is replaced with a PC case within the monitor. As it has fewer parts and is much lighter than the traditional PC, you can take it anywhere, whether it’s to the next room or to your office/home. You might be worried that the best all-in-one computers of 2021 are too pricey but you can get the best all-in-one computers for under $1500 from leading brands. Here’s what we found:
