SPCR & friends featured in MSNBC/Newsweek!

From the TechTV show notes for March 27, 2003: "I want to watch movies and listen to music on my computer, but my noisy, overclocked, highly cooled rig drowns out my speakers.

Katana's Mean Machine: Quieter than a Fish Tank

Do-It-Yourself Systems
James, a.k.a. Katana Man, recently assembled a new system with some of the latest and greatest components for silent PC enthusiasts. The foundation was a D8000 mid-tower case from Coolcases, modded even more with E.A.R fan grommets and AcoustiPack panel damping. Other components included a new 120mm fan Fortron PSU, Thermalright SLK-900U, Zalman ZM-MFC1 multi-fan controller and a BIT Micro Solid State Hard Drive. The result is a speedy system whose noise level is so low that his "fish tank and flourecent lights are starting to bug" him.
