If it was semi affordable, it would be the perfect silent server/HTPC/PVR (quiet) case.
That being said, the case does seem devoid of any nice features beyond its ability to passively cool 95% of components. A way to reduce HDD Vibration is the one that stands out the most. Optical drives are noisy to start with so Id not have expected that to be silenced.
I dont really know what to say. Extremely expensive, probably impractical for a mid-ranged or above enthusiast gaming machine... its a very specialised niche product. Only a product Id consider if I had tons of cash and needed an upgradable and flexible Audio/HTPC/PVR system.
