What hardware is in the computer's main chassis?

A computer host generally consists of the following parts:

Motherboard, CPU, memory, hard disk, graphics card, power supply, optical drive.

Among them, the motherboard, cpu, memory, hard disk and power supply are essential, and it can't run normally without a computer.

Other accessories, such as optical drive, chassis cooling fan, etc., can be installed according to actual needs.

Extended data:

As a part of computer accessories, the chassis mainly plays the role of placing and fixing computer accessories, and plays the role of support and protection.

In addition, the computer case also plays an important role in shielding electromagnetic radiation. Because the chassis can not improve the performance of the whole machine as quickly as CPU, graphics card, motherboard and other accessories, it is not listed as the key consideration in 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 composition:

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.

Materials:

Good chassis front panel plastic adopts ABS engineering plastic, which is firm and stable. If the plastic used for the chassis 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.
