A computer case

The computer case is the metal and plastic box that contains the main components of the computer. It houses the motherboard, central processing unit (CPU), power supply, and more.

Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the floor. The front of the case usually has an on/off switch and one or more optical drives.

Most of the personal computers you can purchase today include tower cases rather than desktop cases; however, some computers are being made with all of the internal components built into the monitor, which completely eliminates the tower.
