We don’t have a guide to upgrade the RAM for this system. Apple made the design much harder than the regular 27” iMac’s which have a RAM access door. Here the system needs a complete teardown lifting the logic board fully out to gain access to the four SO-DIMM slots.

Unless you’ve done a bit of work on the newer 2013 ‘Thin Series’ onwards iMac’s so you are comfortable in taking the display off and have taken out the logic boards I would recommend you find someone who has, as this is an expensive system to get repaired if you make any errors.

OK I’m going for it!

Yes to all of this. And yes to this is not a repair for folks who are inexperienced. It takes A LOT of doing, since the whole logic board needs to be removed, the DIMM slots are on the back of the board. But it's definitely plausible.

This is a procedure Apple will also do for you, but I would totally understand not wanting to take it to them since RAM will absolutely be pricey. And if it is a repair you can do yourself then why bother.
