I've ended up with a number of machines on my network, and a need to name them all in a somewhat logical way. For several years I had them named after the planets, which worked well until the PCs for myself, my girlfriend, servers and Raspberry Pi's quickly summed up to more than the eight planets. I've broadened it somewhat to include any Greek/Roman mythological figure, but the system is definitely not as clean as it used to be.
Do you have a coordinated naming theme for your machines?
My desktop is Eddie (The name of the shop's computer from Hitchhiker's Guide to the Galaxy) and my home server is HEX (the weird magic computer in the High Energy Magic building at Unseen University in the Discworld novels)
