The advantages of aluminum boxes are as follows:
1 lamp
Don't rust.
3 Good color and beautiful appearance.
Disadvantages:
1 aluminum is more expensive than the cost price of steel, the manufacturing process is relatively complicated, and the price is also more expensive than the same structural steel box.
2. Fragility (a scratch on anything is a mark)
3 * * * Vibration (side effect of light weight)
As for the heat dissipation effect, the design of the chassis air duct is more critical than the material.
As for the radiation protection ability, the tightness of the chassis directly affects the radiation protection ability of the chassis. It is not that the thicker the plate, the better the metal conductivity.
Personally, it is reasonable for the chassis to account for 10%- 15% of the host budget. A host configuration of about 1000 can be equipped with 100 ~ 105 chassis. Of course, if the HTPC group is beautiful, more than 1000 aluminum boxes can be used regardless of the configuration.
