In consumer computer products, a beige box is a generic personal computer (or PC) — thus, an Intel PC (colloquially known as a Wintel box) as opposed to a video game console, a Macintosh, or a Unix workstation. The term is also sometimes used to distinguish generic "clone" PCs from name-brand models such as Dell or Hewlett-Packard. Most generic PC cases are in fact beige in color.

A beige box also refers to a standard computer case that is functional and plain.
