Hopefully this is the right section, please move if it's not. I'm looking for hard drive to use in a HTPC. There's a lot of choices out there: Western Digital 640GB, Samsung Spinpoint F1 HD753LJ 750GB, and Western Digital 1TB Intellipower. I am looking for low noise, less heat, and cost. What do you guys think? Am I missing something? With some of the hot deals, I need to make a quick decision. Thanks guys.
