The Concretronic by modder D. Heise may not be the most practical computer, but it most certainly is one of the first we’ve seen that has a case constructed from concrete and steel. To be more specific, “the case for the PC is made from a single, seamless layer of concrete, wrapped around a curvy metal structure made from welding rods and steel sheets, with embedded plexiglas windows so you can see inside.” Click here for the first picture in the gallery.
