About a month ago I decided I wanted to build a dedicated arcade/console machine.  I decided on doing a bar top after the fiance veto'd a full cab or converting an old console record player.  I scoured the forums for examples I liked and tried mocking it up in card board with little success.  Last week I decided to just draw it out on a piece of paper for a stencil and just go.  We'll see if it works out since no real measurements were taken into consideration.  
So far:
Profile:

Monitor Mounted:

Printed out and drilled the standard street fighter button layout 


I didn't think about the fact I'd need to route out the control panel or the fact I didn't have a router so I routed out the top with my dremel tool to mount the 8 way joystick.
Why such far apart spacing?  I can't see myself cozying up that close with someone playing in front of this.  I'm going to put two usb ports in the front for controllers for 2 player console games.  I originally wanted to have two joys and 6 buttons.  Both joys for player 1 but one in the center as a dedicated 4 way.  However now that the joystick and buttons are in place I think it wouldn't look good with another full size joystick.  
QUESTION 1:  What would you do with the space in the center?
A.  Smaller 4-way ball top joystick
B.  Add a roller ball (In the last picture above you can see I have a trackball mouse I could tear apart)
C.  Use the space for graphic real estate
D.  I'm open to suggestions 
 QUESTION 2:
QUESTION 2:  Would you add nudge buttons next to the flippers for pinball?  I just discovered future pinball thanks to this site and it's fun, but I've never really played pinball to know if it's worth having extra dedicated buttons.  I really am trying to keep this as clean looking as I can using only two admin buttons on the front panel (not yet in place) but if nudge/bump is that important to playing than maybe its worth it?
Any insight/comments (positive and negative) you could give me would be appreciated!
