What are Computer Cases?

As a part of computer accessories, the chassis plays a major role in placing and fixing various computer accessories to play a supporting and protecting role. In addition, the computer chassis has an important role in shielding electromagnetic radiation. , Motherboards and other accessories can quickly improve the overall performance, so in DIY has not been listed as a key consideration. However, the chassis is not useless. Some users buy a non-branded chassis, because the motherboard and the chassis form a loop, resulting in a short circuit, which makes the system very unstable.

Computer case

1, standard box type: looks like a microwave oven. The size is about 50CM X 40CM X 30CM. Easy to integrate into home style,

2.Ordinary chassis: As usual, it is the mainstream solution.

The chassis generally includes shells, brackets, various switches and indicators on the panel. The shell is made of a combination of steel plate and plastic, with high hardness, which is mainly used to protect the internal components of the chassis; the bracket is mainly used to fix the motherboard, power supply and various drivers.

Computer case material

Good plastic for the front panel of the case is made of ABS engineering plastic, which is strong and stable. If the plastic used in the case is not hard enough, or it is brittle and easy to crack, the quality is definitely a problem. The steel plate must be at least 0.5 mm or more. The material should be galvanized steel plate with high hardness and elasticity. If it is not thick enough or can be bent with a little force, it is definitely not a good material.

Computer case work

Seeing whether the steel frame has burrs or sharp edges, good cases are often hemmed, at least also polished, which will definitely not make you "scarred" when installing. Second, see if the case frame is sturdy and stable. The simplest is The method is to lift it up and shake it vigorously. If it shakes or even deforms, it is definitely not good. Third, check whether the internal production is professional, such as whether the hole position and size on the chassis are matched when the motherboard is installed, and whether the drive slot and card slot are positioned. Accurate, etc. Fourth, see if there are EMI contacts, that is, there are many small protrusions around the side plate. This can reduce electromagnetic waves and is beneficial to human health. In short, when choosing a computer case, it is important to look at its materials, workmanship, and practicality, and never to be confused by the appearance of fashion.
