Been there. Except in my case it was two 8 story office buildings. Stuff was moved in hastily from an acquired company when there was no room in the server room, hooked up because important (mail server), and subsequently forgotten while departments where shuffled around the building and employees left over a period of many months. A week after I started the server started having issues. And nobody knew where it was... Finally found it in some storage room.
