Well I have pretty much finalized all my cabinet plans with the exception of the cp. I've already mocked it up and it feels good but there's always room for improvements. The buttons are closer to the top to give some wrist room and I placed them in the slanted arrangements for ergonomics like others have done. The trackball is a 2.25" happs with mounting plate and the cp is 25.5" x 8".
Any suggestions?
