Good chassis front panel plastic adopts ABS engineering plastic, which is firm and stable. If the plastic used in the case is not hard enough, or brittle and easy to crack, there must be quality problems. The steel plate should be at least 0.5 mm, and the material should be galvanized steel plate, which is hard and elastic. If it is not thick enough or can be bent with a little force, it is definitely not a good material.

Appearance and material of chassis
Appearance and material are the most basic characteristics of a chassis, and appearance directly determines whether a chassis can be accepted by users. Therefore, the present appearance gradually tends to be diversified, so it also accounts for a certain proportion in our test. The material mainly depends on the material used in the chassis, whether the corners of the chassis are wrapped or not, and the quality of the material also directly affects the anti-electromagnetic radiation performance.
Computer chassis is not omnipotent, and the usual classification factors are the size of the chassis, the way it is placed, and so on. Specific categories include:
1, vertical chassis, this kind of chassis is the most common, mainly for home use, Internet cafes, and assembled desktops.
2, vertical small chassis, this chassis can only use small boards, mainly used in business machines.
3, horizontal chassis, mainly small chassis, mainly used for business and office. ?
