Hey all, I'm thinking of upgrading my HD in my C2D iMac. I've seen the disassembly pictures online, and I thought they look a bit scary! Specifically the bit where you have to peel back the shielding! Couple of questions: 1. Does anyone know how much Apple will charge to do this? If so, can I just bring a HD to them and get them to fit? 2. Has anyone done this? Is it really that hard? I've built plenty of PCs before, but they are a lot more serviceable than an iMac if I break anything (not that I have!). Thanks!
