The Computer Case contains the framework to support and enclose internal
components of the computer. It helps to prevent damage from static electricity. It typically
made up of plastic, steel and aluminum which are available in a variety of styles. The size and
layout of a case is called a form factor. It is also designed to keep internal components cool
