+1 on buying AppleCare from B&H Photo ... great prices!
I have seen many posts from users who have upgraded their Mac computers and then needed AppleCare service. Many were pleased to have the warranty work completed since their upgrade/mods weren't the source-of or contribute-to the problem, especially if the work was performed by a Apple Certified repair shop rather than an official Apple Store. Of course, nobody expects AppleCare to cover non-oem parts or modifications.
If a Mac Pro were to be upgraded to faster CPU chips, would buying AppleCare be at all useful for covering the remainder of the machine, or would one be totally out of warranty for this kind of upgrade (i.e. motherboard issues not related to the slide-out processor tray)?
Any experience or comments? 🙂
