I was taking a look at some small form factor pc’s, and found a link to mini-itx.com. There are some great projects featured heare, including an amazing tube radio conversion, and some fun ones like the NESPC and the E.T.PC.
Even more interesting than the mini-pc’s are the micro-pc’s, like the Cappuccino PCs (relabeled Jadetecs it looks like) or Maxan systems. Pretty neat stuff.
