Hello, I just upgraded my ram to 16gb and the cpu of my 2012 a1418. It had the i5 2.7 cpu and I changed it to the i7 3.1. I have seen a lot of difference. I use this iMac for photo storage since I also changed to an ssd years ago
I was wondering if I can change the logic board to a newer one, which models are suitable and if I can have one that supports nvme ssd and has a better graphics card?
