The PC Case

The typical PC user only knows his or her computer by its most visible components—the display (also called the monitor), the keyboard, the mouse, and the box that houses the main system, called the case. When purchased separately, a typical PC case includes the power supply, cooling system, a slot behind each expansion card position, slot covers over the expansion slots, available external I/O port connectors, and a selection of cables. Figure 1-7 shows the back view of a PC case.
