Please give me your thoughts about my control panel layout.
My main question is the trackball since I haven't played any trackball games yet. Is it better to have the buttons above the trackball or below it? I would think below (as in my diagram) so your hand doesnt get in the way.. but ever example i've seen of others has the buttons above... which seems hard to get at.

My components are all X-arcade stuff, which I'll eventually replace with less clicky buttons.
