Saw MKBHD's imac pro review,  good lawd that thing is factory sealed tight & non upgrade able as heck , i get the AIO "feature" perks are good to specific personals like hardcore office groups who could care less for the features/upgrade-able benefits (all the little bips of tuning & upgrading ,cleaning,maintaining) they just needs something that works silently & wont take up too much space or time fiddling into.

but as a PC user & on that perspective , where the user is robbed of that freedom to even see whats inside & or do slight  manual upgrades & to fix the hardware if anything goes wrong is under the mercy of a payed 2nd party maintenance . that sort of stuff seems absurd & rip off.
