I have a Mame MK cab. The cab had been converted to Tekken2. The artwork was painted black, i tried to save it but it was all scratched up, i pulled the vinyl off and it was all smooth underneath, repainted it black. It has a nice textured look to it.
I made a 7 button layout with some plexy like XtraSmiley mentioned and a posterboard to hid the middle hole (mk3 template ontop of sf). Take the metal plate off the cp before you drill ( i didnt know there was metal

). I kept all the original wires for the coindoorlight and marquee. rewired the joy/buttons/coindoor to work with ipac. Added Esc and pause bottons on oppose top corners on cp. Added two hidden credit buttons on the corners underneath the cp (the design of the front of this cab makes a good location for my hidden credit buttons. Put an RCA connection on the stock speaker to work with my computer speakers setup.
I put a $15 dollar tv i got on ebay as its monitor on a shelf i made from the side of a Donkey Kong cabinet

.......relax, it was a parts cab. The power supply had an outlet, all i had to do is plug the tv in (toothpick trick).
If its a real MK cab i would buy it for $40. You cant buy MDF to make a cab with $40.
(the cab even has wheels on the back so it can be moved)
