I think the faceplate PCB design for the 5.1 surround mixer I'm making for my roommate is pretty much complete now. The big opening is for a panel mount power switch with an LED in it. The slot is for the LCD flat-flex cable that connects to the back of the board with a ZIF socket. The board itself will connect to the main board with a 2x8 IDC ribbon cable (think old IDE cable but narrower).
