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?
I tend to name mine after their physical appearance, though I'm leaning towards space-related names now.
I'll copy a Discord message I sent someone while explaining my naming scheme:
in chronological order:
my very old laptop was black and grey so it was Batman
my first build had orange/gold fans so it was Aurum
my next build was black and white so it was Mono
my current build had lots of RGB so it was Nova (like supernova)
my home server has the BitFenix wings logo so it was Flight
my laptop is sleek and pretty speedy so it was Comet
