Thanks go out to whoever created Understanding Intel Mac RAM on our Guides area - that pointed me to a deal on OWC's site MacSales, for 16GB RAM for a Rev. H (iMac12,1 / 12,2) Intel iMac, for just $160. That deal was too good to pass up. If you're curious why I need that much RAM, I'm going to be running lots of virtual machines. Those eat RAM quick.
