Here's an idea for you... make an "Amiga shaped" case in seethrough perplex. :-)
Or an even better one... "Amiga shaped" in fiberglass look.. wooo cool. ;-)
Ofcause you don't have to be 100% about the size thus saying you could let it be a lil bit bigger so you can fit an internal DVDR, 3.5" HD and a nice BlizzPPC/BVision combo without having to worry too much about heat. :-D
