Well, I'm an ex-MAME cab owner (built a MAME cab out of a Showcase cabinet a long while back, but it was WAY too big for my living space so I sold it and kinda dropped out of the emulation scene for a while) and am in the process of planning a new cab. I've done a search of the boards and saw posts talking about using the original arcade board, or a PS2 w/Drum Controller to come up with a "Drum Mania" like cab...
I have no intention of doing either...
