MODTHEBOX.COM checked out the 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.
