I like to choose computer names after pokémons. The names usually are simple, it's easy to follow some general rule to give names (get the last 9 bits from MAC Address, add 1 and check which pokémon have this National Dex number), you can choose wallpaper colors related with the pokémon color, there's a lot of pokémons to prevent name collisions and new pokémon games which present new pokémons are introduced faster than you have need for new names.
