My warranty on my Al iMac (2.4 C2Duo, 320Gb HDD, 4Gb RAM) is up in January. I was thinking about a couple of upgrades for it to really give it the "get up and go".
1) 1.5 Tb HDD - looking at the teardowns online, this shouldn't be much of a problem.
2) Replace the Core 2 Duo with a Core 2 Quad - The C2D and C2Q use the same pin array and are compatible chips, from what I can tell. Will there be a significant heat increase going from the Duo chip to the Quad? Will the power supply have a problem with the additional cores? I'm looking for basically a straight swap deal, and don't want to particularly perform any heavy duty modifications (especially on the cooling system).
Thanks in advance,
