You can't take apart the iMac, but the 27" model does have user-accessible RAM.

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

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.
