Why are you getting a P4 3.0E if you are not planning to overclock since they are quite expensive for just the additional cache, etc? Air cooling works fine for those chips at stock but overclocking those just pumps out too much heat so that's why water cooling is needed.
You can go with:
Maze4 - 35+
clearflex - 10+
JR-120 - 25+
Via or Eheim pump - 20 -> 50 depending on the model
That's around 110ish, the prices assume you shop around and you have the 120mm fan along with some misc items like hose clamps and a cap for the T-line.
