AND I STILL SAY "USE PLAIN CARDBOARD BOXES!" You should be able to find ones which are the right size, "AND BUY SOME SYROFOAM SQUARES AND CUT CHUNKS OUT!".
PROBLEM SOLVED!
Sorry I had to shout, but it seemed like you were not listening to me
Why does it have to be original boxes anyway, the Amiga boxes were always ugly, flimsy things. Seen the box on the "magic pack"? Or the graphics on my A500 box? Puke inducing!
Now if you'll excuse me I'm off to my "Man Room" (which until now was known as "the Studio"). That was the second best suggestion here, but obviously won't work in a small apartment.
