I read about a similar story regarding old-school Netware (Version 3.x as I recall)... at some university or college, they actually accidentally walled the box in during some renovations; they could see the node on the network, but could not physically locate it (it was buried in a wall space)... it ran for years and years until finally during another renovation they busted a hole in the wall and there it sat; still running. Netware was pretty good stuff in their heyday.
