The Macintosh IIci which was on sale between 1989 and 1993 was a more powerful version of the earlier IIcx and indeed was the most powerful Macintosh for some time. It had a 25Mhz 68030 CPU and at least 1MB of RAM. Now these do not sound much nowadays but back in the day it was a pretty good spec.
It came in a very nice compact case which remains one of my favourite Apple Computer cases. The top is easily removable so you can get at the innards and perform repairs or upgrades. A far cry from today's super locked down units. I'd love a modern Mac in such a case to be honest.
