Swiftech makes some great 2x120mm kits...http://www.frozencpu.com/products/7212/ex-wat-133/Swiftech_H20-220_Apex_ULTRA_Liquid_Cooling_Kit_Universal_Mount.html?tl=g30c83s137http://www.frozencpu.com/products/2385/ex-wat-76/Swiftech_H20-APEX_ULTRA_Series_Liquid_Cooling_Kit_Universal_Mount.html?tl=g30c83s137
You could piece together parts, but I recommend most components in this kit anyway for a beginner. You could probably get by without the NB block, unless you wanted to OC quite a bit. I think it includes the MCW60 GPU block, which is pretty compatible or needs a G80 bracket for $9.
I cool a Q6600 with a DangerDen TDX block, pump listed in those kits, 2x120mm, passive oil cooler as radiator, DD NB block, Swiftech MCW60 GPU on my 9800gtx.
