I need to get an iMac across Canada - help!

So I've got a 27" iMac at "home," where I live for 4 months out of the year. However, I live in Calgary for 8 months of the year, and I'm starting to really want an iMac on my desk in residence.

I still have the original box, with styrofoam.

Does anyone have experience shipping this large piece of aluminum and glass several thousand kilometres? It would all be within Canada - no tricky dealings with other countries - but I'm terrified that I'll take it out of the box in Calgary and find that the screen has a massive crack in it.
