"Water cooling rigs have come and gone over the years, along with the companies that make them. Zalman has been one of the few who made it, and they have done so due to the quality of the products they produce. Not only is the quality good, the performance is excellent. The water cooling unit up for review is the Zalman Reserator XT, which is a stand-alone water cooling system that sits outside an enclosure. This design keeps the hot temperature of the enclosure components away from the reservoir. Also, the Reserator XT is highly expandable by allowing the user to add additional water blocks without having to drain the entire cooling system. Everything needed to get the cooling system up and running is included in one package."
