Well, I myself do not have a custom loop in my case (if that is what you're really looking for) but be prepared for that custom loop to be more... almost definitely FAR more than $150-180. If you're only going to be grabbing one for your CPU, just get a closed loop one. You can get fairly good closed loop coolers for about $100 that will fit a 240mm RAD slot. The other thing you have to think about though is your airflow. If your mobo doesn't support LC or if you go with a closed loop, you won't have as much airflow over your VRMs if you're looking to OC (which otherwise, I don't know why you're getting LC). You also won't have as much airflow over your GPUs. The other thing I would say: I don't know specifically which hexacore you have, be it PhII or FX, but there's an easy upgrade path to an 8320/e/8350/e/8370 instead of getting yourself LC. LC is good if you have the budget for it to keep temps down, but if you getting LC takes out budget from a new CPU, that isn't worth it. An 8350 costs what you're saying your budget is.
