Heh....The future of cheap cases? How do you clean off crayon marks? A mouse ate a hole in my Cardboard server. Oh boy.

I like it - you can go beserk with your own waterpaints etc. The original origami job to assemble - I guess it comes flatpacked And adding an extra blowhole is easy - who needs a holesaw!

But actually could be really silent: gives fairly soft mounting to all moving parts, and I figure cardboard should damp sound better than metal? Also intended for those mini-ITX format Via mobos which are low power anyway. Looks like overall dimensions 188 (W) * 211 (D) * 375 (H) (all mm).

Slightly duff airflow arrangements: presumably the psu exhausts at the bottom/rear, with another exhaust in the middle/rear, and the only intake appears to be closer to the top/rear. Suspect would be better to have that rear case fan as an intake.

Did you look at the 'Himmel' on the same site? There are some pretty slick ideas there, really.

I would like to see at least a carbon-black coating on the cardboard. If not that, maybe a lightning rod? Or fire extinguisher?
