Chosen Solution
I have a 21.5” iMac Mid 2014 A1418 with logic Board 820-4668-A which is faulty. Looking for any alternative logic board I can use which will work in this system. Also one that can support upgradable memory and/or blade SSD supporting logic board.
I found a 1.4 GHz Logic Board that supports a blade style SSD on an external site (iFixit is sold out) but you are limited to 8 GB of RAM because it is soldered to the Logic Board. I did a pretty widespread search but found no compatible Logic Board that you can upgrade the RAM on. You will need to replace the display adhesive strips and I have included a link to buy them below too. http://www.dvwarehouse.com/661-00148-App… [linked product missing or disabled: IF173-005-1] iMac Intel 21.5" EMC 2805 Logic Board Replacement iMac Intel 21.5" EMC 2805 Blade SSD Replacement
