Although a computer case is just a case, don't buy it too casually. Quality is still very important. How to choose a quality case? Let me share this with you.

Case thickness

Many chassis are now thinner, many of which are only about 0.4mm thick and are prone to denting or warping. A suitable chassis is at least 0.6-0.7 mm thick, and even better can be up to 1 mm thick. The above, in addition to not being easily damaged, can also reduce generation of resonance, so that host is quieter, and at same time, it has better anti-collision and is more stable. Of course, thicker case, heavier it is, but given that the desktop is rarely moved, no matter how heavy it is.

Wiring space

The main design of chassis is rear line, so placement of space and openings is very important. The distance between motherboard base plate and side panel of a qualified chassis is usually about 2 cm. If it is only about 1 cm, it is considered very small and wiring is inconvenient. In addition, requirements for wiring holes should not be too high. The main holes are located on right side of installation location of ATX motherboard. There will be a row of three holes. In some cases, they are also located below installation position, mainly for power used. It should be noted that it is best if there is a hole for processor wire, if not, then you need to use a long wire to bypass.


The USB3.0 interface is mostly popular in current UBS interface package. But do not think that there is USB3.0 when you see blue interface. First of all, you should pay attention to interface pins. There are 5 for USB2.0, and 9 for USB3.0. There are usually two letters "SS" next to interface.

Register width

The ATX case is main one. While there are many users of small cases, ATX case is best choice for most people in terms of heat dissipation and compatibility. The normal width of an ATX case is 200mm, but it is better to choose an ATX case around 210mm. Larger cases usually use case fan position, which is more beneficial for heat dissipation. And wider chassis, it's also good for future upgrades. Because performance of current video card is getting better and better, and volume is also getting bigger and bigger, so it's really inconvenient if there is no big chassis.

Dust-proof housing

Dust-proof housing is very important. If you don't want case to be dirty and need to be cleaned frequently after being used for a certain period of time, it is best to choose a case with a dustproof dust mesh, usually installed at bottom or in cooling hole. There may also be a location for fan. It's best to put case in a place with less dust or clean area around case regularly, or you can buy a dust mesh cover yourself and cover it when not in use. Do not use too thick a dust filter in case, denser air circulation, the worse it is for heat dissipation.
