Hey guys! I bought a Marvel v Capcom cab off some dude for 100 bucks and I wanted to make a MAME cabinet out of it. The cab needs some work (ill post pics later) but what Im concerned about is the actual guts of the computer. I have saints book, but some of the answers to my questions arent in there. Now Im a total noob when it comes to this stuff, so bear with me...

I have a garage and space to work on things, but I have NO tools considering I just bought my first house having lived in apartments most of my life, so, keep that in mind haha! I have most of the cabinet intact, the control panel is messed up, I found a replacement on ebay, just waiting for it to be shipped. My main concern is connecting the computer parts to the existing wiring etc.. Here are my questions:
1. Do I need a JPAC and an IPAC? Do they both plug into the PC via a PCI slot?
2. If I plan on using a TV for my monitor (the existing monitor has some issues) can I just plug the TV into the video card that is in the computer (it has a S Video input) or do I need to buy a VGA card?
Im sure I will have more questions when they arise. I just want to thank everyone for the advice in advance, already found so much info on here. Thanks!
