Right now im looking up design ideas on the case.

Also in my search I found a nifty idea on the controller for the arcade controls. Instead of using a USB game pad I was thinking using a cheapy keyboard controller. If you ever played with a keyboard controller you would know what im talking about. If you make two of the contacts touch it sends a signal. For a example Pin 1 and pin 4 make the letter K.

May seem harder but it would be more practical because the MAME's joystick coding sucks and I can add more action buttons.

Don't worry i'll have pictures.
