How do I choose a chassis?

In the DIY computer market, the choice of chassis is actually very important. A high-quality chassis can protect the computer from the interference of external electromagnetic waves, making the computer work more stably and reliably.

The materials used in high-quality chassis are mostly galvanized steel plates, which have high strength, good corrosion resistance, and high relative materials. Steel is susceptible to corrosion when exposed to humid air, while galvanized steel sheets can rely on metallic zinc, which forms a dense oxide protective layer in the air, to protect the steel structure inside. In order to save costs, the shoddy chassis uses cheap tin-plated steel plates, which have very poor oxidation and corrosion resistance, and are very easy to rust.

If the thickness of the chassis is too thin, not only can it not play a role in mechanical protection, but also electromagnetic waves are easy to penetrate, and the shielding effect is greatly reduced. The thickness of the steel plate of a good chassis is generally around the same level, while the steel plate of an inferior chassis is not only poor in material, but also very thin in the steel plate, and the thickness is usually below, and some inferior chassis even only! The average consumer can judge whether the case is strong enough by looking at the internal structure and the thickness of the steel used in the side panels with the naked eye, or by lifting the case to estimate its weight.

In addition to the steel plate material and steel plate thickness, the hardware technology level of the chassis is also crucial. On a high-quality chassis, you'll see advanced hardware processes such as full crimping, keel reinforcement, bump shrapnel, and anti-EMI design. The inferior chassis can be simple, and when disassembling the chassis, the slightest carelessness will scratch your hands.

Expansion capability is also an important condition for the purchase of the chassis, for example, after we install the optical drive normally, some friends will also add *** optical drive and recorder, etc., and some friends install multiple hard disks due to special needs, or group disk arrays. Therefore, the 3-inch slots and 5-inch slots of a case must not be too few, maybe you can't use them now, but when you upgrade in the future, you will encounter unnecessary trouble.

For hardware enthusiasts who often open the case, the design that is easy to disassemble and assemble is even more essential. You'll see this design on high-end cases, such as the side panels are fixed with hand screws, the 3-inch drive racks are fixed with hooks, the 5-inch drives are equipped with screw-free shrapnel, and the boards are fixed without screws, etc., these thoughtful designs make it a lot more convenient for us DIY players.

Finally, due to the increasing heat generated inside the computer and the fact that the computer often needs to work for long periods of time, a high-quality case will have an exhaust fan to reduce the temperature inside the case and make the computer run more stably, especially on the server case. Server chassis usually reserve 2 or 3 12cm fan slots for cooling. Therefore, when we buy a case, we should also pay attention to whether there is a fan position on the purchased case, so as to facilitate the installation of cooling fans in the future, and the fan position is best to have a front and rear one, so that the design can better dissipate heat for the inside of the case.

1. Brand: Choose low-end products such as Jinhetian, Foxconn, high-end such as TT, Cooler Master and other professional chassis brands.

2. Standard: It is best to choose a 38-degree chassis or a 35-degree chassis. The case is designed for better air circulation to facilitate heat dissipation from components.

3. Price: The configuration below 7000 yuan, the chassis should be below 300 yuan (the empty box does not have a power supply), it is not necessary if it is too high.

1. When choosing a chassis, pay attention to the size of the chassis.

Pay attention to the size of the motherboard supported by the case, ATX standard chassis can, with ATX, matx, ITX motherboards, the chassis is bought large, generally no problem, the large chassis can be installed with a small motherboard, but if the chassis is bought small, there will be the embarrassment that the motherboard cannot be installed. (For the specific size, you can ask the merchant to know, or look at the product detail page).

Pay attention to the length limit of the graphics card in the chassis to avoid the case being too small and the graphics card too large to fit. (Ask the merchant).

Pay attention to the height limit of the air-cooled radiator in the chassis to avoid the appearance that the chassis is narrow and the fan heater is too high to fit. (Ask the merchant).

Pay attention to the restrictions on the size of the water cooling radiator in the case, if some cases do not support 360 water cooling, then there is no way to install it. (Ask the merchant).

Second, about the chassis material and the reverse side of the interface, normal are enough, of course, generally speaking, the more expensive the chassis, the better the material, the more reasonable the design, and the richer the interface.

Third, for most users, it is completely OK to choose a suitable size, which is acceptable to you, and at the same time looks like your favorite chassis.

The choice of computer case depends on the motherboard you choose. The ATX motherboard is a large board, and the ATX chassis should be used, and the MATX is a medium board, so you can choose the ATX or MATX chassis. ITX is a small board, and a mini ITX chassis is optional.
