Can I for example buy old 2013 iMac 21,5 and motherboard and screen from 2019 and assemble such a creature? What years of cases are compatible?
Sorry Apple tends to alter things per the different series. Some series have shared a few things but not as large a span as 2013 to 2020 as you are looking at here! 2019 to current 2021 - 21.5” iMac Retina 4K Rear Housing Unit, Apple P/N 923-030792017/18 - 21.5” iMac Rear Housing Unit, Apple P/N 923-016152015/16 - 21.5” iMac Rear Housing Unit, Apple P/N 923-005562014 - 21.5” iMac Rear Housing Unit, Apple P/N 923-000282012/13 - 21.5” iMac Rear Housing Unit, Apple P/N 923-0449
