I have a working JAMMA system from another project, but am very limited on space. So, I was thinking of making a very small JAMMA tabletop cab (I don't have a bar

).
It sounds like the area for the board would need to be at least 12x16x6. I was thinking of putting the board at the very bottom of the cab, which in essence would give me a minimum of a 13.5 x 17.5 footprint if I use 3/4 MDF.
I am debating what monitor to use. I have a leftover Wells Gardner 19" monitor that I would like to use (since it's free), but that would add to the footprint. Alternatively, I could pick up a cheap LCD from CL or eBay.
I've looked around for ideas, but haven't seen any similar projects. Any insight or comments are appreciated. This is definitely in the concept phase (although I would like to get rid of the box of wires and monitor from my workbench ASAP!)
I was thinking of a Neo Geo theme, but there are a ton of Neo Geo mini's out there.
