Is the apple cable Part No. #923-00092 the same as apple cable Part No, #923-0312, going to upgrade SSD only 27" iMac (A1419) to a fusion drive, I ask because the #923-0312 is easier to obtain hear in OZ.
For reference: Intel iMac 27" Late 2013 Hard Drive Cable - #923-0312iMac 27" Hard Drive Cable, Late 2014 / Mid 2015 - #923-00092 While they do look the same, I believe the cables are slightly different in length and it appears the construction is also a bit different. The cost difference is not that much and both IFIXIT & PowerbookMedic (which I’ve posted here for reference) ship internationally.
