Wondering if there is a suggested/recommended tutorial (video preferred) on how to upgrade storage on a new iMac. I viewed a few and some are just so annoying with background music with no one talking. This one is pretty good: http://www.youtube.com/watch?v=K1ls-WoQSls But why do you need to remove the glass panel? Seems like you could just keep it propped up during your upgrade - and one less thing to worry about putting back correctly, i.e. the adhesive that is.
