Power supply suggestions?

When I have a chance, I want to make a supergun (JAMMA box) in a Sega Genesis. The video encoder and controller decoder I've got pretty much figured out, but how to get -5v and +12v I'm not sure on. Any suggestions? I'm sure there has to be some sort of way to get them without using a PC power supply (which I have no problems with doing except that fitting it in a Genesis case would be difficult). Any thoughts? I tried to find the PSX's power supply pinouts but couldn't find those either. I figured maybe I should just add ports on the back to support taking the cables from a PC power supply.

Sence I cant make a url link heres the pin then (courtasy of Gannon)

And if you need 12v a Dreamcast power supply sounds better, it outputs 12, 5, and 3.3 so you'll have any voltage you need.

Yes, but I also need -5v, so if the DC power supply doesn't have that, no good.
I also apparently need roughly 5A on the +5v line. I suppose I'd be needing to look elsewhere for that one anyway.
Any thoughts? Preferably ones that involve cheap stuff

How about a mini-itx power supply? Or if you're planning on just using ac power you could just use a standard itx power supply.

I was hoping for something less costly but I guess there's not much choice. I suppose I'm asking for quite a lot as it is. Thanks for the input.
