I don't have a problem destroying something that I own and hate with a gun, I just would do it out in a big field where nobody is around, or at a range if they allow it (probably not safe if there are other people there though). I've never done it, but I don't theoretically have a problem with it.
I quite frankly would like to take my old computer to a big empty field one of these days, fill it with tannerite, and take a shot with a .50 cal from far away.
Unfortunately, I don't own a .50 cal or tannerite, nor is there a big empty field anywhere around, so I'll probably just sell the parts at the flea market.
