I have a 12 year old iMac 27" that's been flawless all these years - now I can't update the OS, so I've been looking at all the options. I wanted to get another iMac 27" but disappointed the new ones offered are just 24". I really appreciate your content saying it's still worth getting the 2020 27" because after days of trying to wrap my head around which mac mini, which monitor, an external cd drive, and external storage drive, etc my head is spinning. My question is: Over time I have upgraded my current iMac 27" with a 2 Tb drive and upped to 8 gb RAM (installed myself). Are those compatible with the 2020 27"? I.E. can I take it to my computer guru and have them swapped into a 2020 27" if I go that route? Thanks so much!!
