Oh, nos
iFixit keeps on wanting to have all computers be like the self-built things concocted out of parts from Fry's. Fun hobby. Not to do with an iMac. I realize it seems to offend, but the market for a computer you can actually take apart and switch motherboards, small but active. To please the kit builders, you have to put everything in a big tower and insert cards, etc., that are standardized for Windows machines. To please iMac buyers, don't do any of that stuff, because they don't give a damn about changing the processor. (By the way, the original Intel Mac mini, if you bought an expensive new processor, was accessible. I switched around everything else in that thing, but never got around to the processor. A little too much money for a small speed boost.
It was fun doing those repairs. But easier and cheaper to pick up the new model. PS: it's got a fast processor, low-power, up to 32 GB of RAM, and a Fusion drive. Cool. The odds of more than 1% of iMac buyers wanting to open the front glass, crimp but not cut dozens of wires, and get to the processor are less than nil.

If this is a free country then why are you calling my view irrelevant? Or do I not receive freedom of speech because you disagree with my view?
Comrade, all right-thinking people stand together with iPolitburo, who know better how to make Apple products than mere mortals do.
