Back when I was a sysadmin at a university CS department, we always picked namespaces for machines---everything in a given namespace had related names and were identical (or nearly identical) machines. If someone mentioned toque or glenfiddich, you could tell what lab they were in and what kind of machine they were.

I always wanted to use 'Starships from Iain M. Banks' science fiction', which is why no one ever listened to me.

For personal machines, I have been using adjectives that start with 'i'.
