as previously mentioned, Unix admins often name the machines 'cause it makes it easier to admin.
mine were LOTR names like Ruaros, Orthanc, Orcrist, etc for the Unix boxes, and my macs have all been greek or Roman, like hercules (this 15" 1.5pb), icarus, romulus, remus, etc.
I then also named our novell and windows servers after gods, ie Zeus, Thor, etc.
When i did the y2k checks and produced compatibility reports to the CEO at the board meeting, I had a few comments made about the list, but everyone then tried to use the names when they had problems with the servers which made my life much easier (and more fun, too!).
