If you ever bought the A590 HDD and memory expansion for the A500, that came in a superb foam packaging in a sturdy cardboard box. I saved the packaging for years and years, until recently I shipped an expensive Thinkpad laptop in it (with total confidence).
I just cut the foam a bit to make room for the laptop, and used the resulting foam bits to totally lock that sucker down. The recipient was very happy with it too..
