General computing skills are requried (as in, know what the hell you are doing). Time, some space, a clear desk, the balls to actually do the OC'in, the cooling, BOY YOU NEED THE COOLING BADLY. It's pretty crazy in the end once you post benches/cpuz screenie of it. One thing you gotta remember though, OC'in practically voids the warrenty. But in the end, everything is worth it if your computer isn't up in smoke.
