Thanks for the great feedback. I'll definitally look into those other CPU water blocks. As for the radiators, I'll have to check my case as clearance could be an issue between the top of the case and the top edge of the motherboard tray. I'm fairly certain a TFC or XSPC radiator will not fit once fans are included, let alone a push/pull setup. In that case I'll look into how I can best mod the top of the case. If it ends up that I'll have to cut anyways, I'll probably just make room up there for a 120.3.

Here's a question. On your radiators, do you blow air across the radiator and out of the case, or bring fresh air in? I figure exhausting would push hot air out of the case for the benefit of the non-WC components, but cooler air could be obtained drawing in. What do you recommend?
