I’ve been doing some research about replacing the optical drive with my current hdd and adding an ssd to the original hd slot. So far I have found that adapters for the optical drive only accept 2.5" drives. Both of the drives I want to use are 3.5". Is it possible to fit 3.5" drives in the hd slot and optical drive bay? If so, do I need a special part to adapt the optical drive to the hdd? Many thanks!
NO - the space available is for a 2.5 drive there isnt’ an extra inch to be found. study the guide for HD replacement… I have not found a 2008 3.5 optical drive kit for an iMac. If you have one that may be possible there’s more room. I suggest you find the optibay kit first, then the drive that fits it. If this Answer is helpful please remember to return and mark it Accepted.
