Mine are rather uneventfull:
Tombstone, Dragonflame, Transponder, BiteSize, Portege, Breached, Devil, Useless, Crashless, Palmer, Heap.
Not really any general order, just things I randomly picked out of the air. BiteSize for instance refers to my iBook and the fact that it is small enough to just eat in one bite. Breached got it's name since I had to cut out a hole in it's case for a side fan. Tombstone, Crashless, Useless are all old machines. Tombstone being the only one still alive
. Devil being a compaq, imagine
. Dragonflame was cool because I wanted flames on the side of my case, and never got them. Transponder since for about 3 months it was lost in the house somewhere, but responded to ping and SSH. Portege is a laptop. Heap came about when I kept screwing up some programming, and kept corrupting the heap, it was my test machine. Palmer is my machine on the wall. I call it my palmer, since I can carry it around like a tray on my hand because the places where the screws go are just wide enough apart to give me a place to put my hand, and keep it stable at the same time.
School store's computer is named POS-666 (Point of sale device #666), it is the 666th computer we have had to get for the store, that is how much bad luck they have had with them. (It is a cash register/timer all in one, so it "babysits" the fresh baked cookies).
Good luck naming it.
