Is there a way to change the computer name?

I reinstalled OSX from the Panther CD, I skipped the registration page as I had already registered. The only information I had to provide was my name, short name and password. No place for the computer name, the default is DIANA-STEVENS-C, which I hate.

If I had registered Panther again would it have let me name the computer?

I would reinstall Panther (and update to 10.3.7 again) in order to change the name. But I don't want to go back to OS 10.1, which came with the G4 Quicksilver, as it installs OS 9 at the same time and I want it on a separate partition.
