I am not going to try and keep track of names for my guns! I have enough trouble with computer names. I just named two servers Angel and Devil, and the sysadmin named the upper one in the rack Devil, and the lower one Angel. I thought that it would be obvious which one... Well, you get the idea.
On the bright side, if you buy good guns, you can always sell them and get your money back. I just broke even on 5 guns after holding them for 3 years. I was expecting to do better, but I am not as clever as I think I am by half
