basically here's the list of things you'll need after you construct your cabinet :
1 - JAMMA Harness (this is a kick --I'm attempting to get by the auto-censor and should be beaten after I re-read the rules-- harness ... already has certain connectors already on it that you won't have to attach yourslf:

2 - 15 Amp Power Supply (Terry sells excellent power supplies that have a multicolor LED that lets you know when your 5V is in range ... a nice feature (plus 3amp on the 12V line is good too) :

3 - Coin Door (many options here ... whatever design you fancy ... if you going to put this in a pizza place ... also think about adding a security bar ... goes over the coin box door to keep customers out if the machine isn't all that visible .. just a thought)
4 - Marquee Light (fairly straight forward ... you might need a electirc wire and wire nuts depending on what you buy)
5 - Joysticks and Buttons (Start and Player buttons)
6 - (2x) 4" 8ohm Shielded Speakers (many choices here also ... just make sure your power supply will be able to power them ... if you not sure the 4 inchers from Happs are nice and you can go ahead and pick up the grills too)
7 - Arcade Monitor (Wells Gardner ... its and easy choice ... if you got the cash ... get a 27" WG D9200 ... you'll have the option of Standard or Medium resolution which most of the somewhat newer games use. If you feel thats a bit more than you want to put into the machine ... then the WG K7400 is a good choice ... comes in 25" or 27" ... here's the link :

)
8 - Electrical Supplies (Quick Disconnects (.187 and .250), Climpers, Wire Strippers, maybe a few Molex connectors with pins, Power Cord for your power supply, and a power switch so your can turn the machine off without unplugging it. You might as well pick up an EPROM puller ... if you plan to do this for the long haul you'll learn real quick how to ROM swap.
I've tried to remember most of these stuff off the top of my head ... definitely check Bob's site out ... tons of good info there ... good place to start learning
