I know that its possible to replace the flash-storage in the MBA and its also possible to add a third drive to the iMac. But is there any kit to put the replaced flash-drive of the MBA into the iMac? Cases aren’t available (just a USB 3 from OWC) but are there any cables etc.? And is it admitted to mount the naked flash-module as it is in your guide to place a SSD behind the optical drive? thanks a lot

Sadly no, Apple uses custom interfaces on their SSD’s in both the MBA & MBP retina systems. So you can’t install either one into your iMac. As to installing a standard mSATA SSD into your iMac you’ll need a 2.5’’ to 3.5" frame kit if you plan to replace your HD. In some iMac’s you can add-in the SSD as a second storage drive by mounting it on to the optical drive and using a special cable to the unused SATA port on the logic board.
