Wonder what the demand for candy cab blank panels is? I got mine made for 20 dollars. The suckiest part of the whole thing was I had to buy 3 different bimetal bits to drill the holes and those puppies are not cheap. I didn't overthink it. Just put the controls on top about where I wanted them and marked off the holes. The drilling part wasn't too bad except for the 2 1/4" hole. Because I was doing it with a handheld drill, it kept wanting to jump around or get stuck. I had to do a little sanding and refining once the holes were done, but with an overlay and the fact that most of the buttons overlap the holes, every imperfection will be covered over anyway. BTW, I got Paradise Arcade's 2 1/4" trackball and it fits fine with room to spare. It plugs into the computer's mouse port if you are doing mame. Not sure what it would take to go the jamma route.
