Presence is reasonable. The computer chassis has a lot of functions.

It must be known that the main components of desktop computers are monitors, chassis, mice and keyboards. For the display, mouse and keyboard, most users understand their role, but for the role of the chassis, many users do not understand, let's take a look at it! First, it provides space for power supplies, motherboards, various expansion boards, floppy drives, optical drives, hard drives, and other storage devices, and these are supported by connectors, brackets, screws, or clips inside the chassis. The parts are firmly fixed inside the case to form an intensive whole. Second, its solid outer casing protects the board, power supply and storage equipment. It can prevent pressure, shock and dust, and it can also play the role of anti-electromagnetic interference and radiation to shield electromagnetic radiation. Third, reduce the temperature inside the chassis for ultimate refreshment. Fourth, it also provides a number of easy-to-use panel switch indicators, etc., making it easier for the operator to manipulate the microcomputer or observe the operation of the microcomputer. Now everyone knows that the role of the chassis is more than just a shell. A good chassis can effectively protect the internal hardware from damage. Therefore, in the process of purchasing a computer, the budget of the chassis must not be ignored.
