The early Rev3 machines had a molded logo.
I guess they're rare, but not rare in the $1000 on ebay way.
I think I still have two of those cases in my cupboard somewhere.
Thanks! I didn't know... I have seen just rev.5 machines as I remember (even if a friend of mine had an A500 with Commodore keys, but I don't remember a C= molded logo on it).
Would be nice to have it too...
