Alright, somewhat of an update. It's totally playable now, its running like a dream. Had no problems with the wiring and the ipac, everything worked first try.
There are 3 things left to do: The marquee (laser engraved layered plexi side lit with blue LED's), key board drawer, and get a piece of glass cut to go over the bezel and monitor. Other than that, it's practically done. Oh, and I'm eventually going to swap the white player start buttons for black ones, it should make the CP look a bit better.
Here's some photos, share your thoughts.
