A computer case (also known as a computer chassis, cabinet, box, enclosure, housing or simply case, or sometimes incorrectly referred to as the CPU) is the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse). The case and its contents are called the system unit.
There are several patterns, such as tower and base unit; These names are also used for a system unit built in such a case.
Cases are usually constructed from steel (often SECC — Steel, electrogalvanized, cold-rolled, coil) or aluminium. Plastic is sometimes used, and other materials such as wood and even Lego blocks have appeared in home-built cases.

“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“We all know the Navy is never wrong, but in this case it was a little weak on being right.”
—Wendell Mayes, U.S. screenwriter. Otto Preminger. CINCPAC II (Henry Fonda)
