I’ll take non upgradeable ram for a new design or better cooling. Can’t stand the design and the temps are insane.I think we'll get one OR the other of your wishes on the next refresh. If they improve the cooling it'll be with the iMac Pro's cooling system. If they redesign they'll probably dumb it down and reduce the cooling capabilities even more in order to make it smaller. Either way we're losing the upgradeable RAM.
