DIY PC enthusiasts should have gotten wind of this environmentally friendly, recyclable PC case already. Manufactured by Japanese company Lupo, it is constructed entirely out of cardboard. All you need to do is remove perforated sections of the cardboard into the respective parts, fold along the lines as directed, and voila! A perfectly functional PC case that’s biodegradable. I’m not too sure what happens should a component overheat and burn the entire case into a pile of ashes though.
