Actually, I could use one of those ITX boards..... a square biscuit tin, a rom, an fdd, a slim hdd, a tiny psu.... don't need much else.... plus I could cut it with tin snips.... build a frame inside... interesting idea anyway...
One time I had an old 486 working on the kitchen table... with no case. Everything was sitting on the table. My parents said I was "thinking outside the box."
