I have a question about getting an iMac. I want to get an iMac since I am about to get a desk that has room for it, but I don't know what older model I should get. I'm looking at the older aluminum ones, with the Core 2 Duos inside, but can they run Mountain Lion, if not Mavericks? I wouldn't be getting the fastest model, just getting it to have something to use at home instead of my MacBook Late '08. I'm looking at something with similar specs (Core 2 Duo 2GHz, 4GB RAM, etc.). Do those models have a Mini DisplayPort, or will I need a micro DVI adapter to hook up my second monitor? And finally, would a Mac Mini be something else I could look at as an alternative, something with a Core 2 Duo?
