Windows gives examples of "Kitchen Computer" or "Mary's Computer" for setting the name of a computer (Computer Name tab in System Properties). But I'm sure that most people don't name their computers that way and show off a bit of creativity in it.
Previously I used to use names from Asterix like GetAFix for my main dev box. Now I exclusively use names from Hitchhiker's Guide to the Galaxy. Some of the machines I use are named as below
What name do you use?
