for cpu waterblock i would recommend the D-Tek Fuzion thats in sale @ 54$ instead of 64 for the member of HWCF, also for radiator i just ordered a Thermochill PA120.3 radiator that use 3 120mm fan and it should be more then enough for a quad and a video card .. its also for sale @ 99.99 instead of 143$ for the member of HWCF
just check out the sponsor deal section ;)
tubing i would go 7/16'' and pump i would drop off a Swiftech MCP655 , reservoir could also be a switech micro res. with all that, and your full coverage block for your 4870 you should have a full watercooling setup
just checkj my worklog, i will start it when my part will arrive, that could give you a nice idea of what you can do
