I'd like to pre-buy my RAM for the 27" iMac that I'll be ordering (hopefully) soon. It would be nice to have the RAM in my hands when I get the iMac. From the Apple website, it says 1600MHz DDR3 so this should work, right? http://www.amazon.com/Kingston-ValueRAM-PC3-12800-Notebook-KVR16S11/dp/B0089JIDUI/ref=lh_ni_t I'll order my iMac with the minimum around of RAM (2 x 4GB for 8GB total) and then I'll pull those out and put in 4 x 8GB of this RAM for 32GB total. $144 plus shipping. Pretty good deal. Just wanted to run it by everyone to make sure this RAM will work fine. One of the reviews on Amazon says they used this RAM in a late 2012 Mac Mini and it works. So presumably, it will also work fine in the late 2012 iMac.
