According to applicability
An All-in-one PC system has all the hardware and monitor components built into one case common, so that the entire system is contained in a single unit.
The main advantage of such a system is the reduced space occupied by it. There is a wide range of all-in-one systems, the differentiating factor is provided by the diagonal of the screen, specifications and design.
Choosing an all-in-one system is useful when you want a powerful and compact PC system, on which in the future you will not want to intervene to change the configuration. Unlike a desktop PC whose configuration can be modified in the future, an all-in-one system usually only allows the upgrade of the RAM memory and the SSD/HDD unit.
