I'm considering getting a Mac mini, to use solely as desk-bound storage for my music, videos and photos, to dock with my iPhone and iPad. It won't even be used for video playback, only light activities such as playing music over my bluetooth speaker, or viewing photos. I do not do much editing of photos, so it would be more for organizing them. I don't think I need much speed or power for these activities. I do my actual work on my Macbook Air. Any reason not to get the 500GB Mac mini model and attach a $100 hard drive to it, rather than springing for the more expensive 1TB models? I'm trying to keep the cost of the Mac mini plus accessories less than what I'd pay for a second laptop, so that the purchasing decision makes sense.
