Wondering if anyone here has heard of the 5,1s starting to fail or give aging issues by now, or if it's almost unheard of. I'm mainly referring to stock specs used since release. Storage drives, RAM, even Video card are easily replacable with brand new items with fresh lifespan, but Processor and Logic Board, not so much. Due to the fact it's nearly impossible to find new or barely used 5,1s, you would only even be able to replace with used parts. But correct me if I'm wrong if new/never used Logic Boards/Processors can be found. I am hoping those two parts are not the ones that have aging issues.
