They are pretty much plug and play with JAMMA. For games that only use 3 buttons. For games that require more, a kick harness is needed, and this varies for every game. Everytime you switch boards you will have to adjust the monitor, so get a cab with easy to reach controls. Only other thing to think about is the monitors. Arcade games typically come in 15khz, 24khz, or 31khz. Most old stuff is 15khz, while new stuff is 31khz (VGA). 24khz isn't used by much other then Sega System 24 (Gain Ground, Crackdown), Model 2 Model 3, and Konami's Gradius IV. So if you want a Naomi for example, you'll need a 31khz, and you'd want a tri-sync cab.
