My girl is in the granite business, so I was actually considering making a granite case in the next six months.

My question is why hasn't this been done yet? Beside the ease to work with it, I think it is a better material than wood.

Sure it is heavy, but it manly too. I was thinking something along the lines of taking the rails and interiors of a full case. Using L support bracket and silicone to connect everything. I might also reuse the back of the case to simplify alot of mounting the power supply.

Then using a water jet cutter to cut any of the fan holes.

Sure it might cost 400 dollars but, you wouldn't need to paint the thing ever.

Don't you think a granite case would be crazy badass.
