Stop what you are doing right now and head on over to TweakTown to read Shannon's review of the Cooler Master Silencio S600. For comparison purposes, you can see our evaluation here.
When I first saw the Silencio S600, I knew it had the potential to take make a good spot for itself among the silent PC case category. When I started building in it, I feel that like most Cooler Master cases, it is well put together and does its job, while offering good features.
