Chosen Solution
I recently acquired an iMac 27 late 2014. It appears to have a factory install of a 256 gig SSD drive. When I open it up, there is an empty bracket for a conventional 4 x 6 hard drive, but no SATA cables. I suspect that the 256 SSD is a type M2 affixed to the underside of the main board. I already have a 5 TB hard drive that I would like to install within the empty brackets, but I need four post screws. I have purchased a SATA cable from iFixIt. Need suggestions where these 4 post screws might be obtained. What might their specs be?
@paud those are hard drive pins and are Apple part number 923-0377 Available on here and they might get them back in stock at this place
I have just been advised by someone at OWC that this iMac 27 (serial #D25PG057FY14). equipped with a factory install of a 256 Gig type M2 SSD drive, never had headers on the main board to accept a conventional 4 x 6 hard drive, even though empty mounting brackets are there, waiting to be used. I just bought a SATA cable from iFixiT for this computer, with no mention by them that there may not be SATA headers on the main board. Thoughts of others? Regards, Terry
