Can someone help me? I've gotten a new iMac late 2013 21.5" i5 2.7 with 1tb hdd. I want to add a ssd on the pcie slot but can't find anything that's says "yes this is the part number you need". I'm fine with the install, going to do the ram at the same time and only open it once. I just can't find any definitive answer as to which ssd module will be compatible. Not wanting a fusion set up. Want apps and os on ssd and photo library on hdd.
