Noxide, welcome to AT!
It seems like a lot of the people here are just plain jealous. There's always that someone who ruins it for others. Don't pay much attention to people like that. If you have the money to buy the stuff, good for you! If I had the money, I would definitely treat myself to some goodies without investing a lot of time looking for good deals all the time.
Definitely Lian Li for the case, Antec or Thermaltake (or one of those reputable companies) power supply, and Raptors are the fastest out there right now for HD (I think). Definitely a few of those. Recently, I actually saw a review about some case that has silent cooling with all these heatpipes running inside the case. Also, I saw a Peltier case with a small condenser inside that doesn't make much noise. You might want something like that. It will be so cool to have a silent but lethal system. Try not to trade-off loud noise for extreme overclock for an everyday use computer. You don't want a vacuum cleaner. It will drive you up the wall.
