They are the first iMacs since 2012 to offer such expansion / upgrade facilities. Earlier this week Apple held its annual WWDC, where quite a lot of shiny, slim new Apple hardware (and new OS software) was launched. We duly noted the first content creator professional targeted iMac, the aptly named Apple iMac Pro, and also a pair of powerful and sleek new iPad Pro tablets, again fishing for high-end content creator customers. With such headlining products the refreshed iMac line didn't earn many column inches. However, as revealed by a new iFixIt teardown, the refreshed Kaby Lake iMacs are the first since 2012 to feature a non-soldered Intel CPU, and the first to offer removable / upgradeable RAM since 2013.
