As part of the computer accessories, it plays a major role in placing and fixing the computer accessories, playing a supporting and protective role, in addition, the computer chassis has an important role in the shielding of electromagnetic radiation.
Chassis from the structure can be divided into at, atx, microatx, nlx, wtx (also known as flex-atx) and so on.
atx chassis from the style can be divided into vertical and horizontal two, the two styles have advantages and disadvantages. Vertical chassis internal space is relatively large, and due to the principle of hot air rising cold air falling, vertical chassis power supply in the upper, its heat dissipation is better than the horizontal chassis, adding a variety of accessories is also more convenient. But the vertical case is larger, not suitable for use in a more narrow environment. Horizontal chassis either in the heat dissipation or ease of use are not as good as the vertical chassis, but it can be placed under the monitor, can save a lot of desktop space, previously used by the commercial computer. In the current market, we can generally see are vertical cases, horizontal cases have basically been eliminated.
