ok, want cheap watercooling, follow these instructions... i did it and its cheaper than any wc system (well under 100bucks)
step one: go to a junkyard and get a heatercore from an old car OR find an abandoned car and take it (it is legal to take things from an abandoned car if it has been there for two weeks or more to be considered abandoned) cost varies
step two: order a pump, more specifically, the the via aqua 1300 should cost 30 bucks shipped (got mine from xoxide, but there may be cheaper places around)
step three: make a waterblock by taking a copper heatsink, cutting off an outside fin or two, and brazing it all together, you may need to get thicker sheet of copper to braze to the top with the inputs and outputs being copper pipe about one inch in length and brazed on.
step four: get tubing and elbows as needed. make sure you get teh reinforced tubing, its way better. my local ace hardware had it for 123 a foot, it was 3/4 od, 1/2id and NEVER kinked.
step five: get a T fitting and cap while your at ace, shoudl be a dollr each. cost for all things at ace: 5bux for tubing, two for fill/bleed system (T piece with cap), and a variable amount of money for elbows.
step six: while you're at ace, get four nuts, four springs, and some washers, and a piece of metal to go over the top of waterblock. shoud cost about 4 dollars for all things to mount the waterblock with
step seven: fabricate the piece of metal mentioned above such that you can mount the waterblock
step eight: leak test, cost: free and maybe saving you lots of money, then fix any leaks
step nine: mount the waterblock
step ten: break out your favorite tool for makign big holes in cases, then cut out a hole for your radiator and attach it with your choice of a shroud, zip ties, screws, silicone seal, or whatver you feel like. add a 120mm fan or more if you feel like it
step 11: mount the pump somewhere
step 12: put all tubing together again, test system with comp turned OFF
step 13: fix any leaks
step 14: if you really feel 31337, go buy a 170w peliter off ebay, get a coldplate, modify your mounting system, insulate like mad, and be amazed at what you can overclock to (you may need a new psu for the peltier, i recommend replacing your current one with this if it cant take the extra load on 12v rail

step 15: play with fan voltages to see what you can get away with. i can have 2ghz stable with NO fans on in my system (psu is execption), but i use a mobile barton at 1.375v
step 16: go play games and enjoy ;P
