u should consult my sticky on watercooling. I describe exactly what a reserator is, and its basic features on it.
The kit is not really worth it in my perspective. My NAS which uses 3 undervolted yates, will get wayyyyyyy better temps, at a tad bit more sound.
The reserator1 had massive pump failure issues. The 2, i dont know.
The main pool for water is made out of aluminum, so that basically screws you on most aftermarket upgrade blocks.
Id suggest piecing a custom for the same price. Or getting a kit at petratech.
Links to stores are on my sticky! please leave a feedback if you do happen to go to it.
