Mine are named after fictional robots, computer programs, or AI. It started with my wifi being GLaDOS for 5 GHz and Wheatley for 2.4 GHz. I thought it was funny that everyone could immediately tell that Wheatley was the slower one. Over time, I continued the trend. My gaming PCs are named after characters from the Mega Man X series (desktop is Zero, laptop is X, steam deck is Sigma). My macs are named EVE and WALL-E. My server is named Sibyl System (from Psycho Pass).
