Guess I'll be first again.
I would just suggest skipping the "kits" all together and just buying the hardware Like I did. You'll be ok just so long as you take your time and do the proper research. Don't be afraid to ask stupid questions.
All things are not created equal so I wouldn't go out on a limb for the newest greatest thing. Stick to tried and true setups.
hmm. :/ i was thining of useing a pillar drill from school to make a water block for my cpu gpu and northbridge useing 1/2 tubing and any old radiator i can find at a friends scrap yard... how much cooling would the radiator need in the way of fans and how would i power them? pluss how powerfull would the pump have to be?, i was thinking of putting the cpu and northbridge on the same circit with the gpu waterblock on a seperate circuet. any tips on the design for the water blocks and is there any advantage to haveing multipul in's on the waterblock - ive seen a cpu waterblock with 4 ins and 1 central out.. or the other way round.
