Types of computer cases
The case protects the computer's component parts and holds them in place.
It also protects you from some of the electrical fields that the components
give off. The size of the case helps determine what can be added to the
computer.
Computer cases come in two configurations:
Desktop
A desktop case sits flat on a surface, taking up more than 2 square feet of
real estate, 3 to five inches high. Many people put the monitor on top of the
case. This saves desk space, but usually raises the screen too high to be
comfortable for your head position. The thinner the case, the more convenient
it is to place, and the less room it has for expansion.
Tower
A tower case sits on its end, either on a stand that keeps it out of
floor-level dust, or on the floor. Towers come in several sizes.
