Cereal PC. Using a cereal box, old, classic, new, or original artwork, with a PC inside. The difficult part may be balancing it so it does not fall over all the time like cereal boxes tend to do. What am I saying? The whole thing will be very hard! Where to put the optical drive? Fan?
I hope the box is thick enough for the heat sink to fit inside. A frame inside could strengthen it, and a foil lining inside may protect the paper from heat. I emailed 3 pictures to add to this post. Thank you for this contest.
