I know it looks like there isn't enough room but there is. Take a look at this side view of the cab.
The bottom of the "monitor box" measures 18 inches long and the vertical beam is 4.5 inches thick so that's about 22 inches. Each square on the paper is equal to 2 inches. Eleven blocks = 22 inches. Must be one of those optical illusion things.
The thing I like about this design is:
1) Not a huge footprint. I love the showcase cabs but they seem to take up a lot of room. This cab is only about 2 or 3 inches deeper and wider than my Mortal Kombat cabinet.
2) Like a showcase, the control panel could be whatever size or shape you want. No constraints. Even my positional guns would be far enough from the screen to work properly.
3) That modern look (I love classics too, so don't flame).
