hey y'all, i did a bit of searching on the forums but didn't find what i wanted. Is it better to upgrade ram myself or take it into an apple store? i have a 2.16 ghz c2d with 1 gig of ram. I also will need to upgrade my hd in the fututre (i have the 120 gig hd) and plan to buy an external with firewire. So i wanted to ask what is better to do, take it into apple store (i have apple care) or upgrade ram myself, or buy an internal or external hd? also does anyone have any suggestions for a good hd (external or internal)? Thanks for any input.
