1. It provides space for power supply, motherboard, various expansion boards, floppy disk drives, optical drives, hard drives, and other storage devices, and through the support of metal parts in the chassis, brackets, various screws or clips, etc. These parts are firmly fixed inside the chassis to form an intensive whole.
2. The outer casing protects the board, power supply and storage equipment, and can prevent pressure, shock and dust, and it can also exert anti-electromagnetic interference and radiation functions to shield electromagnetic radiation. It also provides a number of easy-to-use panel switch indicators, etc., allowing the operator to operate the microcomputer more conveniently or observe the operation of the microcomputer. The cabinet is generally painted and electroplated to prevent rust, forming a protective film and anti-static on the surface. The internal design of the chassis is specially instructed: the quality of the chassis is less lacquered and plated. The chassis with low cost difference will be sprayed and plated in the box. In the past, the assembly of the chassis was indispensable for fixing the fasteners, nuts and studs. Now there is no screw on the outside of the chassis, and the interior is also improved. The push-pull design is used to fix the internal components with plastic clips or to set the bayonet when processing the sheet metal chassis, which is convenient for disassembly and assembly.
