How do you look at the role of sheet metal processing?
When you look at the steel plate, the steel plate must be thick and shop around. When you tap it with your fingers, you can feel which thickness is thinner.
Second, look at the spray paint, a qualified cabinet, all the steel needs to be painted, and the spray paint must be even, so that it can be excellently rust-proof, dust-proof and so on.
Third, look at the architecture planning. Generally speaking, there are many baffles and there are cooling holes. Some iron sheets used to fix the cables should be covered to prevent damage to the cables. The side wall fan should be installed on the rear wall of the cabinet due to most of the heat generated at the rear of the unit.
Looking at the accessories, since the device includes network cables, telecommunication cables, and power cables, it is necessary to purchase hook-and-loop belts or toothed belts to effectively secure the cables in the cabinet. It is better to assume that the cabinet has a cable management module that allows the cable to be secured directly into the straight unit rail.
Fifth, look at the glass, the glass must be thicker, but also pay attention to whether there is crack in the periphery of the glass. If there is a crack, it means that there is a hidden danger, and it is necessary to pay attention to whether it is a hand.
Six look at the function: the earliest thinking should be security.
Seven look at the heat, estimate how much heat your equipment has. In general, there are two or four fans on the top of the cabinet, and the fans are more and more good. There are also some screws, nuts, etc. used to fix the frame, but also sufficient. It will not cause troubles in the lack of accessories due to future expansion.
