The Mame cabinet is now finished! I decided against a full bezel since the TV itself fit the entire cabinet length. I added a 1.5" board on the front of the TV shelf in order to tilt the TV at the same angle as the cabinet sides which now gives it a finshed look.
I also decided to mount the X-Arcade console to the base so that it didn't move during game play.
The kids really enjoy it!
