Inspired by this tiny gadget, a thin client in a wall socket, I got thinking about hiding away your computer in the wall. I came up with this solution…
You could probably hack the Jack PC thin client so that you have the corresponding connection on the wall-facing side of the socket. That would enable you to run cables down from the attic and simply plug into the wall socket, and install.
With that sort of setup (although slightly hacky), as opposed to being a thin client and requiring a Terminal Server, you would literally have a PC in the wall that you can just plug into. You could even have a whole network of PCs.
Of course, the original design of this is meant for thin clients, so converting it into a solid PC would defeat the point of the thin-client-ness. Thin clients are there to save money, and my idea basically just hides away your ugly PC case, and puts it into a nice neat wall socket where you just plug in your monitor/speakers/keyboard/DVD/Blu-ray drives.
