Recent convert, I purchased a MacBook Air when they first came out. I love it for travel, but need a powerhouse for music production at home (ProTools, etc.) I have to go out of town for business for two months and was thinking of buying a MacPro to use there and then shipping it home. 1) Would it survive UPS in the original box? 2) Should I just buy the standard configuration from the local Apple Store then upgrade RAM & HD myself? 3) Any downside to doing this? Thanks, in advance.
