Corwin tips me on this casemod in progress by Domovoi, featured on a Dutch computer forum. It looks amazing, as far as I can see from the Sketchups.
It's based on two Flärke TV stands linked together, with a media center PC, power supply and all necessary cabling neatly tucked away inside. The Sketchups and photos give a pretty good idea how it all fits but, sadly, I can't seem to find a final picture of the hack. Or is it just that I don't read Dutch?
