WOW, that is one expensive PC, but I am a poor college student. I think you may be paying to much for your liquid cooling setup though. I put mine together for under $100 using a Danger Den radiator, reservoir and CPU cooler, I bought the water pump and tubing from Lowes for $15 and some water wetter from Napa (I think). Granted, this was over 2 years ago, but to me, $300 sounds like alot. Anyways, if I have one word of wisdom, buy Water Wetter! It will not breakdown like anti-freeze and it keeps all the coolers and tubing looking like new. I had to replace my coolant 2 months after I got my liquid cooling setup because I used anti-freeze and it broke down (turned into a milky-white goo, it was gross). Just water will discolor your coolers from oxidization and lowers thermal efficentcy. I've been using the water wetter stuff for over 1.5 years now and everything looks like new. Uhhh yeah, I'm rambling, looks like a fun machine! Good luck.
