Styrofoam packing does come with the boxes. Axiom probably will charge you for the boxes, it isn't much.
I did this 4 years ago when I moved.
Funny, now that I actually paid for the boxes, I don't thow them out.
For electonics it seems like if you want to sell the item, you can get a few more bucks for it if you have the original box. I think there is a perception that if you keep the box, you take better care of the item. seems silly to me though.
