PC Cases

A Pc cases, also known as a computer chassis. It is the enclosure that contains most of the hardware of a personal computer. The components housed inside the case (such as the CPU, motherboard, memory, mass storage devices. Power supply unit and various expansion cards) are referred as the internal hardware. While hardware outside the case (typically cable-linked or plug-and-play devices such as the display, speakers, keyboard, mouse and USB flash drives) are known as peripherals.

With small holes (mostly in the back panel) that allow ventilation and cutout openings that provide access to plugs/sockets (back) and removable media drive bays (front). With hardpoints and through holes for mounting internal hardware, case fans/coolers and for organizing cable management.

The external case panels, at least one of which are removable.

Sizes and Terminology

Consequently, personal computer form factors typically specify only the internal dimensions. And layout of the case. Form factors for rack-mounted and blade servers may include precise external dimensions as well since these cases must themselves fit in specific enclosures. Moreover,.

For example, a case designed for an ATX motherboard and power supply unit (PSU) may take on several external forms such as a vertical tower (designed to sit on the floor, height > width). A flat desktop (height < width) or pizza box (height ≤ 5 cm or 2 in) designed to sit on the desk under the computer’s monitor). Full-size tower cases are typically larger in volume than desktop cases. With more room for drive bays, expansion slots. And custom or all-in-one (AIO) water cooling solutions. Desktop cases—and mini-tower cases under about 46 cm (18 in) high—are popular in business environments where space is at a premium.
