Hi My friend just bought a new system and is selling his old. He is also selling his water cooling system. It's a Zalman Reserator. My question is , is it good? If yes,what's good? If no,what's bad? I'll also get a WB5 for the CPU, a NWB-1 for the NB, a GWB3 for the GPU and a RWB1 for the ram on the graphics card. Is this good? He also said he had a "peltier", if I would like to buy it. What is a peltier? The price he gave me for the entire water kit (not the "peltier" included) is about 3000SEK (300€ euro) [+-]. Is it worth the money? Excuse me for all the questions, but when it comes to water cooled systems I consider myself as a total idiot (I know nothing about them).. Thanks for any replies.
