Ok, have been away for a while, sorry about the delay in replying.
Re the thermaltake case, awsome bit of kit.....totally wasted on the linuxmce system. The touch screen doesn't work at all, and because linuxmce doesn't do dual display, you could only use the screen if you weren't using it as a hybrid, i.e. in a cupboard and not connected to a TV. The other great features that I was expecting to work, such as the built-in IR receiver, media card slots etc don't work either. I would say don't waste your money on it if its for a linuxmce system.
The rest of the system is working most of the time. The hard drive is very noisy, and you can hear it even though its inside a cupboard in the lounge. The graphics card doesn't do sound over the HDMI, not sure if its a driver thing, or what, so I have to use the optical output from the motherboard and feed it into my amp. This causes a bit of a headache because linuxmce then has to select a different sound channed from the video channel when watching anything from the core on my TV, but it does work. However when trying to watch live TV through the hybrid its so pixelated that its unwatchable. Saying that, I have a Zotag MAG in the kitchen which works great as a media director, and you can watch the live TV on that with no pixelation whatsoever, which is weird as its using the same capture device. There is a slight mismatch between the sound and video when watching live TV on the MD, but I only use if for watching the news so haven't gone out of my way to fix it yet. Watching any movies that were ripped to the core works great on the MD and the hybrid, both audio and video work great on both.
Over all I'd say that my unit is way over specced for the use it gets, and having nice new graphics cards etc doesn't mean that they wil work ootb like with windows systems. I'm considering getting one of the Dianemo units and keeping this box for my home PC needs... undecided at the moment though.
Hope that helps.
