High-end chassis: generally around 1, yuan, luxurious configuration, self-provided power supply, strong heat dissipation capacity and fixed measures, beautiful appearance and relatively strong price-_-!
Mid-range chassis: this kind of chassis is the one that we usually equip. Generally, the mass products provided by big manufacturers (such as Colorful, aigo, Jinhetian, etc.) have a general appearance and are relatively strong. Generally, they have their own power supply (which can be exchanged for other power supplies), and the price is about 1 yuan (including power supply).
Low-grade chassis: generally, it is about tens of yuan, and the power supply is not equipped or low-grade cannot be used. If money is tight, This kind of chassis is characterized by very low material consumption, thin chassis, and generally poor magnetic shielding, which often occurs due to design problems (such as hard disk bracket activities, etc.)
It is divided into ATX and BTX2 types according to the architecture type (excluding the previous old-fashioned architecture)
ATX: The chassis architecture that is widely used now is characterized by using ATX power supply (nonsense), and the vent of the power supply is set at the upper part.
BTX: Recently, Intel withdrew from the BTX architecture in order to realize its strategic attack on AMD, mainly by moving the power supply fan to a new position to make the air inlet duct closer to the CPU. (AMD has to redesign the motherboard in order to adapt to BTX)
38-degree chassis: The so-called 38-degree chassis is a solution for cpu heat dissipation, that is to say, a hole is cut in the side of the chassis, and then a filter screen (some of which have chassis fans and cooling ducts-a cover) is placed to make the cpu fans take cool air directly from the outside instead of from the inside of the chassis, so the CPU temperature can be reduced to about 38 degrees. (Actually, the design of the 38-degree chassis is not good. (Personal opinion) As you know, the CPU fan is a big dust absorber, and it opens a hole to suck air out, which really becomes a vacuum cleaner-_-! )
