While it ultimately comes down to what’s inside each computer, more companies build powerful, top-of-the-line desktop towers than all-in-one computers. Often, a tower will also give you the ability to open it up and upgrade individual components, which is helpful for gamers and tech-savvy users who want to upgrade their systems. Among casual PC users, picking between an equally powerful tower and an all-in-one system comes down to convenience. The all-in-one is a single piece of equipment that you just need to plug in to use. A desktop tower requires you to set up more peripherals, which takes longer, but also offers advantages in the long run.
