This could be a fake!
Someone like DVD really has no reason to sell his beloved Amiga epecially since he had a blast :lol: wit it. I mean money is not an issue for him, he can probably sell his shirt and get more money for it!!, hell the real DVD might build a room, encase his amiga in glass forever!
I guess there is no "case" for the tower because it already has a signed autographs from DVD (got DVD to autograph it somehow) on the case so if someone requested it Vola! the case shows up with DVD's autograph.
Just my conspiracy theory
