About a Year Ago i Bought This iMac off of Ebay for a cheap price. fully working to my suprise, i changed the hard drive to an ssd, and it has currently 4gb of Ram. I’ve seen many videos and guides both on youtube and ifixit of iMacs getting Cpu And/Or Gpu Upgrades. Most memorable to me was the 2007 20” iMac And the Cpu Upgrade. Im currently running MacOS Catalina Patcher on my iMac and it is running good, although i would like to (if possible) to upgrade the Gpu. Any Help Is Appreciated.
Pretty sure all Intel iMacs can support CPU upgrades, as even the new ones have socketed CPUs. It’s going to be a chore though + your CPU choices are limited. GPU is a complete no, as that’s soldered onto the motherboard unfortunately.
