I had a 2010 imac (before redesign) and I actually moved back to China in 2011. So rather than selling it and taking a hit, I decided that I needed a computer anyways so I just brought it with me. I brought it in a checked luggage. Check out the picture.
I had a big suitcase and managed to take up one side with just the imac. I bought some industrial foam and stuffed the sides. I had to use a T10 torque screw driver to take apart the stand (look online, ifixit for instructions) and just stuffed the machine into luggage.
Came back, assembled the stand. Its still my main machine at home. I had a problem with the screen, and Apple China replaced it no problems.
