I just bought a 24" Intel Core 2 Duo iMac and I wanted to know if the 2GB of memory from my 20" Intel Core Duo iMac is compatible. Also, does anyone know where to buy a 2GB stick of RAM for the new 24" iMac? I can't find it anywhere and I want to use the full 3GB allowed in the new machine. Oh, and I'm selling my 20" Intel Core Duo iMac that I purchased May 13th of this year. It's in pristine condition and I can take some pictures if anyone is interested. I'm selling it for $1,275 including shipping and that also gets you 2GB of memory (or 1GB if the RAM is compatible with my new 24" iMac). It also ships in the original packaging. PM me for more info or offers.
