Aaaaaand the opinions are off! I'll start off with MY personal opinion of this piece o kay-rap...
I bought one SIMPLY for the sake of a silent-pc. The pump stopped working about 4 hours later and burned up a barton 2800. This was when the 2800 was pretty expensive. It took a long time for me to get over my burning hatred for ThermalTake. The blue light kept shining through the pump, but no pumpee. Water did not move. It was nice and quiet though =p.
Now... the GENERAL opinion on this thing is even better. Looking past MY personal failure story, you'll get soooo many bad comments on it you'll possibly swear off water cooling in general. Pump sucks, resevoir sucks, water block sucks, radiator is *decent*, lines are too small etc etc. The *backup* resevoir is slightly thicker than Zip-Lock baggies. It looks like a mild wind could put cracks in the thing. Seriously... the average Mountain Dew plastic bottle would work better.
And THEN there is the idea of overclocking... The thing barely keeps up with a *decent* air-heatsink. You could get the same quality of cooling from a $10 heatsink. NO reason to spend $100+ on something this worthless. And the 'silent' PC excuse isn't even justifiable... $100 could buy you 3 or 4 different Air-Heatsinks that would cool better and be just as quiet.
Cliff notes:
WORST COOLER EVER
