Like a few others on thingiverse I had trouble with my cat jumping on my PC and hitting either the power or reset button. There were a few covers like this on thingiverse, but nothing for the mini g. The front of the pc case slopes down and so you will need to line up the cover accordingly. There's a small mark in the model to help with this. I used a little silicone caulk to attach it to the case. No support needed for printing. Print in two pieces and snap together. The side is beveled to give a better view of the activity light.
