Computer cabinets are fitted with doors and side panels (which may or may not be
removable). Cabinets enclose a rack, which is a frame that provides a means for
mounting electronic equipment. Cabinets come in a variety of styles, colors, and
many contain baffles, fans, and other features.

The terms rack and cabinet are often used interchangeably, which is
incorrect. The rack refers specifically to the frame that provides a means for
mounting electronic equipment, while a cabinet is fitted with doors and side
panels.
