During the 90's there wre ads for Commodore 486sx pc's that looked like Amiga style cases.
I remember the very first time I saw the ad in a UK Amiga magazine I though some New Amiga was in the works. After the liquidation of commodore a Canadian Amiga dealer advertised systems called the A3200 (or something like that) They used silimar cases from what I could tell in the ads. Those particular shots were tiny.
Can you post shots?
