Sorry didn't see your thread, must've glanced over it , my bad..
I don't know much about that pump, but the other components are good. Water vs air is quite a BIG difference. One being the cost another being the time it takes to setup. With water your going to need a lot more than that.
Needs a pump, radiator, water block, tubing, clamps, water, water additives, a fan(s), barbs, shrouds, etc... etc...
It's really up to you. But performance wise, the apogee will get you farther in temps and overclocks. It's just a matter of how much you want to spend. Hope this gives you something to chew on for the time being.
option 1 or or the ultra 120 extreme? or is it too hard to decide?
