I don't think that's the right pack job to ensure the safety of the PC. I used to frequently travel with LCD monitors and would pack them with more protection than you used for a full PC.

It's not even the baggage handlers it's just how bags end up in the hold.



That's a typical 737 baggage hold. If your bag ends up on the bottom all the weight from the other bags could have caused what happened.

Sorry to see what happened but I think some nice rigid foam would have gone a lot further than the bubble wrap.
