The K1 was designed to prevent vibration at high speeds, and I designed it to prevent this. I hope you will like it. It does not prevent the ventilation of the motherboard and power supply. You do not need to remove the bottom cover.

The support is only required where the rubber feet shown in the last picture will be attached.

16 pieces M3*35 to connect the parts together and you can use the original screws for the rubber feet.

I hope you will like it.
