Yeah, I have the black buttons from x-gaming in there right now.  i was hoping I could use a couple of the leaf buttons for my pinball flipper buttons, but I'd have to do some crazy routing to get them to work.  

It's mainly the extra switches I need for some stuff.  (Coin rejector credit button, and 2 for my ultra-special keywiz max mod.
(Push in keyboard drawer, close switches = keywiz active, pull out keyboard drawer, open switches = keyboard active.
