I recently built a bartop for my office and figured I'd post it up here.
I used the kit from North Coast Customs.
I ordered the the panels blank, and made a few changes to it.
I put a soundbar where the marque should have been.
I also added some graphics i found online and a 1/2" plexigrass panel, to survive the beating that "track and field" puts on the cab.
It also has a usb port in the front and an ethernet port in the back for adding games, configs, etc.
I went with 4 buttons and a spinner . I used maximus arcade as the front end.
The stick is a sanwa JLF, buttons seimitsu, and the spinner is a BYOA token topped turbotwist 2.

Let me know if you have any questions!
