Anandtech posted a review on the The AlphaCool Core Storm XT45 and Core Hurrican XT45 Liquid Cooling Kits A quote from the article:

As summer kicks off in the Northern Hemisphere, today were bringing the water to our PC cooling testbed with a look at a pair of kits from AlphaCool’s range of ready-to-install liquid cooling sets. Specializing in liquid cooling, the German firm offers a complete range of liquid cooling parts – from radiators and reservoirs to tubes and connectors – both on an individual basis and as part of complete cooling kits. These kits essentially are collections of individual parts that are conveniently packed together, saving the trouble of picking items one by one and getting everything needed for a CPU liquid cooler at a small discount.
