Solved Is Rear Housing Compatible For Imac Late 2013 And 2015 Imac Intel 21 5 Retina 4K Display 2015

Chosen Solution

I have a late 2015 iMac 4K (21.5) Power button broke. There is late 2013 rear housing on sale on eBay. Is the housing compatible? Both have the same A1418 number on the back?

Here are the parts in question for reference: Late 2015 iMac 21.5" Rear Housing Unit (15) Grade-B - Apple P/N 923-00556 Late 2012/13 iMac 21.5" Rear Housing Unit (12/13) Grade-B - Apple P/N 923-0449 There are some differences between these while minor will make using the the older case difficult as the microphone is located at a different location and the WiFi & Bluetooth antenna’s are located differently.
