Apologies if this has already been pointed out, if you'd like to have a complete MorphOS/Amiga styled MacMini case.. AKAIK that's not the new "flat" Intel-based MacMini so if you're willing to try.. Think I'm going to design something slick (err, hopefully), my eMac with MorphOS is so good that I'm planning to buy a Mini as well (eMac is really a bulky and heavy sucker ).
PS: the online design editor requires Flash.

Interesting. Too bad that the costs for shipping to Europe appear to be prohibitively expensive. The price for the skin itself is very fair.
