The only negative is with the case installed, you don’t know if it is powering on when you hit the button, because there is no fan noise or HDD noise (I used SSDs). So you have to peek in the top vent to see if mobo lights flicker. 😀

See if you can find a Monsterlabo case. They went out of business, but their fanless cases are all heatsink so zero noise.

I picked up the itx model and overspecd the power supply so that the power supply fan never turns on either.

Reminded me of this.
