Silverstone is now designing special heatsinks designed to keep the noise down in their new upside down case, and it comes with a windtunnel too.  SilentPCReview looks, and listens to see how good this case is.
“The flagship model from Silverstone is a tall mid-tower aluminum-steel hybrid with a host of unique features: Upside down mounting of the motherboard, a “wind tunnel” duct that directs the airflow of two 120mm fans in push-pull mode across the CPU area, separate thermal zones, a hinged front bezel, etc. It might just be the best thermally and acoustically optimized PC case we’ve looked at so far.”
