Because the chassis is not like CPU, graphics card, motherboard and other accessories can quickly improve the performance of the whole machine, it is not listed as the key consideration of DIY. However, the chassis is not without its merits. After some users bought a chassis with a miscellaneous brand, the system became unstable because the motherboard and the chassis formed a loop, which led to a short circuit.
Chassis generally includes shell, bracket, various switches and indicator lights on the panel, etc. The shell is made of steel plate and plastic with high hardness, which mainly plays the role of protecting the internal components of the chassis; The bracket is mainly used to fix the motherboard, power supply and various drivers.
Extended data,
main feature
1, 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.
2. Measurability
The development of computers in the future is always elusive. The more prepared you are, the more you can meet the future needs. We mainly investigate the distribution and design of 5.25-inch optical drive and 3.5-inch floppy drive and hard disk.
3. Features and functions
Depending on whether the chassis provides front USB and audio input/output interfaces, we will personally experience its ease of use, such as the guide rail installation of hard disk and CD-ROM drive or the tool-free installation of board cards.
4, dustproof
For most users, dustproof may be the least consideration, but if you plan to keep the chassis clean for a long time, you should look at its dustproof degree. The dust-proof performance of cooling holes and the dust-proof ability of PCI baffle with expansion slot are mainly investigated.
5. Heat dissipation
For computers with increasing calorific value, we can't ignore the heat dissipation performance of the chassis. It seems that installing more fans has become the mainstream of DIY. We mainly consider how many cooling fans it provides or the reserved position of cooling fans and the number of cooling holes.
