Al the larger HTPC cases on that site are from Silverstone. The HFX case was about $500 US the last time I checked. That didn't include a power supply nor CPU heat-pipe.

You can check the prices yourself easily though. The HFX should be easier to get in Europe than it is here in Canada or in the US. What you install in the case is up to you - and that can go from simple to lavish.
