I'm coming up to the end of my 1 year warranty on October 27th. I'm debating between buying Applecare or not. There is no way I'm going to the store and spending $300, but I was figuring if I buy one with the box, unopened on eBay, it could work out. Just a question though, if I replace RAM/HD will my warranty be voided? How about if I use the colorwareservices?
