When I came to my current position, every PC was named for the original user. Over time this became disorganized and a spreadsheet was used to track the computers. Not only that, the CEO and other executives had their computers easily identified on the network.
We changed the scheme to location-OS-AssetNumber. The help desk people hate it and say it is difficult, but they still have to use the same spreadsheet. Plus we have the bonus of simple asset tracking for the help desk. The benefits are obvious.
To be sure, obscurity is not a complete solution, but it does make it harder for the mail clerk to to find profit/loss statements on the CEO's desktop or personnel records in HR. It's just another layer in a comprehensive solution.
I've used Greek mythology for servers before as well as location/function schemes. The scheme I inherited used movie characters. I've discontinued it for a different system. It's completely unprofessional to have a COO call the help desk to complain about Yoda problems.
