I know this board tends to frown on Mame to some degree but....it would be cool to build a cockpit like that from scratch to play a wide range of space themed games. Galaga, Gorf, Zaxxon, SI...the list goes on and on. A LCD (another no-no on KLOV) would help to slim down the cabinet design some.
I think the key to a "great" build would be a design that can be easily broken down to move the game around...make it easy to get into the basement or around a tight corner. I have to admit, I'm not familiar with that cabinet design and perhaps it does breakdown.
