If I were spending 30k on a rig the size of a trashcan, I wouldn't be trusting delivery anywhere. I'd buy a $150 ticket to BFL and fly it back home personally.
It would be faster, for sure. But also, like musical instruments, you could probably do that. Just buy an extra ticket for your package, like people do for cellos, and belt it down. And if they didn't want to allow you to do that, a word with the stewardess and baggage handlers would probably be enough.
"In this package is extremely sensitive computer equipment. It is also very, very valuable. Can you please, please, please be extra careful with it."
It would be enough 999 times out of 1,000.
