Hey there, so I finally settled most of my debt, now its time to get something for myself. I'm thinking of upgrading the hard drive inside my 20" Intel iMac, but I've read up a few snags from some people, like an overheating HD, or a loud one. I've done my searching, but I haven't really seen anyone recommend a specific one. So from the great community, what do you suggest (Brand, Speed) to be my iMac's new HD? I'm looking towards a 500GB. I don't do any heavy editing or processor work, but I do have a big movie and music collection in conjunction with my Apple TV. Hope to hear from you 2 hours till my 24th bday, have a Heineken for me pls!
