Thermaltake VC4001SNS Mozart HTPC Case
 

The top panel of the case has a couple of perforated areas to help aid in cooling, by allowing fresh air to enter the case. The rectangular portion is in the video card vicinity, while the octagonal one is in the CPU area. The underside of the case has the usual gold plated audio style feet with foam sliders. We can also see the perforated section along the front that allows air to enter the case for the front mounted 80mm fan to aid in cooling.
