I've passed on the Macbook Pro so far because i was always told opening it voids the warrenty. I have another thread asking about the case design in regards to replacing the hard drive, but maybe that's the wrong question. A guy over on Apple's forums claims opening it does NOT void the warranty. So technically I could get one, crack it open, swap the drives, and keep the spare to swap back in if I need warrenty service. Anyone know for sure? I think I'll have to ask about actual difficulty in another thread. I've built my own computers, but the Macbook Pro's innards look tiny and scary to deal with to me.
