Here's my dilema. I have a 2009 24" iMac with a 640GB hard drive. I want to upgrade it to a 2TB and have the ability to do so. The problem is that the LCD underneath the glass in the top right corner is slightly damaged. Im not sure how it happened being that my iMac hasnt left my desktop since I bought it. Anyway, I had planned on buying AppleCare before the warranty is up and was going to have them fix the LCD. BUT, if Im not mistaken, upgrading the hard drive would void the warranty. I really dont want to void the warranty seeing as I had planned on buying AppleCare but I really want the 2TB hard drive. I had planned on taking my iMac to my nearest Apple Store sometime soon but, being as I am a graphic designer, being without a computer is bad for business. So Im just looking for some opinions. Should I void the warranty and upgrade the hard drive and not buy AppleCare and ignore the blemish on the LCD? The blemish is noticeable but not a distraction. It looks like some pressure somehow was put on the top right corner and theres a slight hairline crack and some discoloration around the area. I want the big hard drive because I have an almost 1TB iTunes library and right now its on an external and is slow. I want to have my full library on the internal and use the external to back it up.
