Posted by admin in Computer cases (also known as a computer chassis, cabinet, box , enclosure, housing, or simply case ) are the enclosures that contains the main components of a computer. It is sometimes referred to as a CPU, referring to the primary component housed within the case; this was a more common term in the earlier days of home computers .When peripherals other than the motherboard were usually housed in their own separate cases. Cases are usually constructed from steel (often SECC- Steel, Electricity Chromate Coated), aluminium , or plastic, although other materials such as wood, plexglas, and Lego have also been used in case designs.
Computer cases can come in many different sizes (known as form factors) . The size and shape is usually determined by the form factor of the motherboard, since it is the largest component of most computers. Consequently, personal computer form factors typically specify only the internal dimensions and layout of the case. Currently, the most popular form factor for desktop computers is ATX, although microATX and small form factors have also become very popular for variety of uses. Through the 1990s , most of the cases had simple rectangular shapes, and were often painted beige. Beige box designs are still found on large number of budget computers assembled from generic components. Some cases include built-in I/O ports on the front of the case. Such computer accessories also include the wires need to connect ports, switches and indicators to the motherboard.
