Watercooling. It used to be synonymous to overclocking, at least until mainstream manufacturers like Apple started including watercooling options in their systems. Zalman's Reserator 1, an imposing tower designed for watercooling might look like an extremely powerful unit, and looking at the cost had us believing it would be. Our tests, however, gave us a whole different picture. The highs: it's quiet, looks good, and easy installation. The lows: high cost, lack of mobility, and mediocre performance. The lowdown: If you're looking for silence, this is worth a look. If you're looking for pure performance, look elsewhere.
