What is Chassis?

In computing, a chassis (also sometimes called a computer case, tower, or enclosure) is the frame or structure that physically houses the internal components of a computer. It provides structural support, protection from physical damage and electromagnetic interference, and airflow for cooling. Chassis come in various form factors (e.g., ATX, Micro-ATX, Mini-ITX) that dictate the size and layout of components they can accommodate. They are commonly used in desktops, servers, and other computing devices to organize and protect the hardware.
