My main server is named Postulate (an idea that you assume for the sake of argument), my desktop is named Axiom (a proved postulate), and my backup server is named Corollary (an idea that follows from an axiom).
Mine are also literary. They are references to Sanderson's cosmere series and the names chosen reflect their purpose.
I have an old optiplex SFF which is called Preservation because it has a disk drive for ripping media, it's a disk wiping station for repurposing drives, and it's old hardware I'm preserving.
