MAME cab building advice

[Satoshi_Matrix]

Hey guys, I have a Neo-Geo MVS cabinet that Id' like to mame. I don't know the entire history of Neo-Geo cabs, but mine seems to be a conversion as it's actually mostly pitch black, not bright red like all the typical beauties I've seen. It's gutted and just the cab.

Basically I'm looking for info.

1. Anyone have a checklist for what kind of PC/PC parts I should get? I need the PC to run MAME and maybe a few retro consoles and that's it.

3. What kind of price point am I looking for for the PC mame setup itself? not including monitor or arcade controls, I already have those.

2. There's nowhere really for a keyboard or mouse. I'd need to be able to move through any menu using the joystick. Is that a problem?

Thanks.
