I only recall one instance of anyone wanting their machine to be exactly like a real arcade machine, and that was someone who had a defender in good shape that developed a problem and so he wanted to put a PC into it and have it boot up and play defender.
Of course, he didn't build the cabinet, becauase it *was* defender.
Most people want cabinets that play many arcade games of different styles, and they make cabinets to accomodate that, including extra controls and combinations of controls that were never in any arcade cabinet.
And most people choose to express thier own personality in the details and finish of the cabinet, although a few people do choose to replicate an actual cabinet.
