So I have wanted to do this for a few months now and I started to search for the case that I have always wanted to have :The Apple Mac Pro case.Two days ago I found one for sale for $50,so I bought it, an got it delivered today. My plan for this build is the following : Find a cheap mATX case->Get the motherboard tray from it->Cut the area of the Mac Pro case where the motherboard tray/IO Shield will stay->Get rid of the scratches on the case->Paint the case->Mount the PSU/HDD/D
