Can you actually install additional RAM? I didn't know you could take apart an iMac; i thought that changed after their "unibody" one piece aluminum design.
It is by far the easiest! It is a very thoughtful design, nothing like your average PC where upgrading the RAM is the same experience as it was 20 years ago.
Funnily enough, it's probably easier to replace the RAM in one of those Mac than any other consumer PC. https://youtu.be/1nQp_Yb8YW0?t=55
