If I had it to do over, I think I would just pick up Pandoras Box, a JAMMA control panel, and a VGA LCD. The performance of the Pandoras Box is poor with intensive stuff like Metal Slug X, but it's fine up to SF2-ish era games. SF2 is my red line for performance.
Right now I'm what I guess is the typical Chris thing... X-Arcade and some PC parts.
