Finally, it's ready: my very new, special-ordered media pc. I mainly bought it to replace my (rather noisy) old pc with it, and to have a real looking PVR thingy.
Want to see pictures? Of course you do...

Half-front-side view, along with the big, silent fans.

The rear of the case, displaying HDMI, Audigy and TV tuner, among other things.

The internals of the case, displaying the various system components, like in any other system, really.

The line up: from bottoms up, the media pc, the radio tuner and amp, the cd player, and my MP3 player's at the top.

The system will be running Gentoo Linux, with MythTV, of course. Aside of the media thingy, it will host various files and stuff, mostly media things, like recordings, and photos. Note that I most likely have to rewrite some of my installation guide to keep up with the various changes in versions and hardware.
