I'm buiding my first PC from scratch and after copious research have arrived at a watercooling solution, PolarFlo TT blocks, DTek CSP X2 pumps, a Dtek Pro 120 Rad, and a double bay Rez. (Two cooling loop format). Yes I think I can fit that in a PC-V1200 case. (smile) I understand a little bit about Ram selection (likely corsair low latency DDR3200 2 512's) and well probably go with an Abit or Asus mobo. I've heard about these mega over clocks on 2.4 and 2.8 P4's and some what less impressive results with later model P4's. The highest OC i've heard of has been just over 4 gig's with a P4 3.0E. (stable?) I was wondering what the expert opinion was for your best bang for the buck OC over say 3.4.
