I've been looking into this one (to ease any possible buyer's remorse from buying the Thermaltake Silent Water for $69.99 =P) and the one I posted earlier and from the reviews the Thermaltake Silent Water seems to have better performance. As well as the hoses on this one come out of the side of the waterblock, so they can interfere with ram and other components nearby, whereas the TTSW water block enters from the top.
Actually, to be honest I'm not 100% sure that this one has tubes that enter from the top since the pictures on the website and other places don't seem to show it clearly. If it's based on one of the other "Mini" units such as the R80 or R120 then it does have the water-block with the hoses coming in from the side.
