I am the owner of a 20" iMac 2008 2.4GHz Core 2 Duo, with 4GB of ram and a 250GB HDD. A few questions: 1: Can I upgrade the HDD to a Crucial M4? 2: What would I need? I am looking at the M4 64GB. Would I need a 2.5" to 3.5" adapter? what kind of screwdrivers? 3: Is there a good guide anywhere to the installation? Will I run into any kind of fan issues as on the current 2011 models? 4: Is there 2 drive bays like the 2011 27", so that I could keep the 250GB in as a data drive? 5: On snow leopard, after iLife, and Office, how much space would I have spare? 6: Will I run into slowdowns If i fill up the SSD? Or is it advisable to keep 5-10GB of space empty? Thanks a ton guys.
