Thanks everyone for the tips so far. I've added the extra pinball buttons and moved the launch button.
I've added some more pics on my Tumblr Blog
http://cocktailarcade.tumblr.com/ A run down of the pics is on the backside of the arcade cabinet a draw that pulls out for use a as a desktop pc and all so for analog flight stick games like Afterburner. as well as a projector stand for arcade on the big screen. as so you would notice the screen tilts both directions what not shown is the second set of gas struts(lazy with Sketchup).
Also the cabinet is not yet pretty looking I have to learn a bit more Sketchup but soon it will rock.
oh and already got plans to change the 4 player panel and make a forth side panel with the flight stick and spinner also add a dedicated Happ analog flight stick and second 8-way flight stick for tank style game.(pics up soon)
