Hi, I am new to the mac community. I just ordered a new MBP 13" , stock model. I saw some threads on the site where users suggested that I upgrade the RAM and HD by myself and save a few bucks. I found this deal for RAM and am struck on what HD should I buy as a replacement. I am looking for a 500GB hard drive. Is there any better deal for RAM than the one I have mentioned? Also do I need any tools other than the Torx t6 and Philips #00 screwdriver ? Thanks in advance, Pogo.
