Well I may be buying my emac tomorrow. The girl in the mac store gave me the price and inlcuded the applecare 3 year warrenty and extra 512bm of ram (both with additional costs) I noticed tlater on that the price was pretty expensive for this extra 512mb sd-ram. I have 3 questions: 1. The ram that comes default with the macs, emac in this case is just generic sd-ram isn't it? therefore the extra 512mb of ram she was offering will no doubt be generic too. 2. Can the emac take pc133 sd-ram or pc100 (or both) 3. If I say no and get some nice brand (Crucial) ram elsewhere and put it in myself would that void the warrenty at all? thanks.
