Installation steps:
1. Twist on tiptoe: Screw all the copper screws in the chassis, not just a few. The motherboard will be damaged if it is not completely connected for a long time. The reason why this nut is put first is to isolate the motherboard from the chassis backplane, which can create conditions for heat dissipation on the back of CPU.
2. Install the position of the chassis baffle.
3. Put the motherboard into the chassis, and align the screw holes on the motherboard with the footstool screws on the motherboard.
Just tighten the screws.
