Hi, I bought my macbook in January 08 so its a Later 07 build of the line. Im considering upgrading its ram to 4GB, considering this product. http://www.ebuyer.com/product/142437 and my HDD to 320GB, considering this product. http://www.ebuyer.com/product/136790 I was wondering 3 things:- 1. would these products be compatible? 2. That installing these yourself is end user allowed by apple? 3. and would this void my 3 year apple care that i have on my macbook?
