iMac EMC2805 Logic Board Replacement

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.

回答此问题 我也有这个问题

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.
