I have a new project "Night Wind" based on the Antec Sonata. I've got 2 Barracuda drives, 6800GT with NV5 Silencer, Zalman 7000CU, Antec NeoPower PSU and a 120mm coolermaster rear fan. I made major modifications to the front intake and have all the fans hooked up to my Aerogate II. With the fans on low, I can barely hear it at night and still runs cool
