Thanks for looking and thanks for the compliments.
This is my first cabinet, so I expected to make a lot of mistakes (and I did!). I hid most of them, but the "too small a marquee" is chief among them. Just a first cabinet mistake. Not only would it have a looked better with a larger marquee, but with the speakers and the lights in there, it's very tight fitting. It was a real PITA to wire up the speakers and lights.
I'm an old school player (I'm 31), so I wanted to iconic characters as my side art. My wife works for a sign company, so she did all of the graphics (with way too much input from me

The marquee is some sort of backlist plastic (polymere or something?). I'll ask my wife and get the details. The side graphics were are plain vinyl. We used vector art from

Since I posted the pictures I have worked on the bezel. I've used black vinyl to "outline" the TV (so now there's no more grey showing). I'm also working on a better bezel. My first attempt (the one you see) didn't work out as well as I had hoped (I took a piece of lexan and painted it black except for a space for the monitor to show through). It looks like crap up close, but it's serviceable for now.
I'm running all of this on a Athlon 800 (very slow, no NBA Jam, MKII, etc. for now) with 256MB RAM. I'm using Win2K with Mame32/GameEx as my frontend. I would highly recommend GameEx for anyone considering a good frontend.
