After overclocking for years with Panaflo 120mm fans(old aluminum ones) and using Antec cases with front metal removed where the fans are located, I decided to try watercooling. I went all out and ordered a Koolance 601 case ready to run. I am using an Abit IS-7 m.b with Twin LL Corsair DDR400 memory(2 512 sticks), a retail P4-2.8C cpu and easily overclocked to 3.5Ghz at a constant 30-31 celsuis temp. I also am using ATI 9800pro, Maxtor ulstra133 7200 120Gb & 80Gb hard drives, Klisph ultra promedia 5.1, Audigy2 soundcard, Samsung 191T LCD.
I haven't tried to go any higher as the system has been extremely stable and very good perdormance. I just wanted to try something different and get it out of my system. Watercooling is very expensive if you purchase ready to go. Mine cost $470 with shipping,extra hard drive cooling kit, video card cooling and extra accessories.
You guys be the judge. It's a very quiet system, but expensive.
