The PC case is a thin sheet metal enclosure that houses the motherboard, power supply and various drives (HDD, FDD, CD, DVD).
- Cases are offered in two styles, desktop and tower. Today the tower
type is predominant. It stands upright and is much taller than it is
wide. It is usually placed on the floor next to, or under a desk. The
desktop has a pizza box profile and usually sits on the desktop.
- Tower cases are offered in two basic sizes, one that can fit
ATX (12" wide) motherboards and one that can accommodate ATX mini (8.5"
wide) motherboards. The number of drive bays offered also varies
depending on manufacturer.
- The motherboard and power supply mount to the floor at the rear
of the case. The drives (hard, floppy and CD/DVD) mount in enclosures
called drive bays at the front of the case.
- Cases run from $20 to $70 depending on size (ATX or ATX mini), number of drive bays and the wattage of the power supply.
