I have a Core i3 3.2 Ghz iMac and just picked up a Core i5 2.3 Ghz Mini to use as a media machine. Can I shuffle some ram from the iMac to the Mini safely?
Models are listed by year, not processor. If you don't know the year, you should be able to find out from the Wikipedia articles on iMacs/Minis, which list the processor, memory and hard drive options on each iteration.
