A computer's case is the most externally visible component of a computer, with the possible exception of the monitor, keyboard, and mouse. The case houses all the major computational devices of most computers—the motherboard, CPU, hard disks, expansion cards, and so on. A poor choice in a case can cause you grief for months or years to come, as you struggle against it whenever you upgrade some other component or curse its ungainly size. Checking a case out in person and looking for a few key features can go a long way towards ensuring that you have a computer with which you can live.

One of the most important components of a case is the power supply. The most important issue in picking a power supply is to get one that supplies adequate wattage to the components that reside in the computer's case. The 235W power supplies that are common today are adequate for most modest computers, but if you expect to load your system up with lots of hard disks, internal tape drives, half a dozen expansion cards, and so on, you might want to look into a larger power supply.
