There’s no PCIe slot on the EMC 2889 motherboard???
It depends!
If you got a SATA drive’d model then that is correct! No PCI/e SSD slot.
But! If you got a Fusion Drive’d model, or one which has a SSD then your logic board DOES have the PCIe SSD slot

Hi, for iMac 16.2 no Fusion Drive and no HD/SSD, there aren’t EMC for upgrade/repair? I’ve searched in all place, OWC Aura Pro 2X isn’t compatible with 16.1 and 16.2… I think this model can be only repaired or upgraded (maybe only repaired) in Apple Store. This is right? Best regards
Both the 2015 21.5” iMacs iMac16.1 & iMac16.2 (4k) offer a 8.0 GT/s PCIe x4 custom blade SSD connector on SSD only model as well as with the Fusion Drive model. A straight HDD system will not have the slot hardware!
The problem you are seeing here is the 21.5” A1418 only supported PCIe 2.0 x4 where the 27” A1419 supported PCIe 3.0 x4. The older SSD’s Apple used where PCIe 2.0 x2.
Apple didn’t use the PCIe 2.0 x4 SSD very long which is why you need to stick with the real Apple SSD in this series requires.
