Computer Cases

Computer cabinets are fitted with doors and side panels which may or may not be removable.

Cabinets enclose a rack, which is a frame that provides a means for mounting electronic equipment and parts. Cabinets come in a variety of styles, colors, and many contain baffles, fans, and other features. The rack refers specifically to the inside frame that provides a means for mounting electronic equipment, while a cabinet is fitted with doors and side panels. The cabinet must allow air to come in and, after it has done its work cooling the parts that would otherwise overheat, to go out. The cabinet should permit the mounting of a filter to keep dirt, dust, smoke, human and pet hair, etc., out of the computer works. The average computer has two fans, one in the power supply and one attached to the computer chip that constitutes the main processor. Without a filter, the fans will deposit a lot of dirt throughout the cabinet, and onto and possibly even into the drives. This may eventually produce read/write errors, and place those errors onto your backup media as well; lost data is the result. It is also possible that eventually your fans will get so clogged up that they will fail and permit the computer to overheat, slowing performance, producing lockups, and eventually shutting you down completely.

Your cabinet should be tough, and it should have a sturdy locking device so that you can control access to your computer. These two characteristics are especially important whenever critical data needs to be protected. Make sure that the cabinet contains all of the rack capabilities you will require, and that it is rated for the correct wattage of power. Some of them come with the power supply already installed.
