I'm about to go off to college, and I want to get all my computer stuff ready to go. Here's what I'm thinking: I will plug the ethernet in my dorm into an old airport express my friend gave me, I will plug my printer and external hard drive via usb into the airport. That way I'll have wireless internet and printing in and around my dorm as well as a way to use time capsule wirelessly. Would all that even work? Any hard drive suggestions? I was thinking a 500gb should do. Maybe this one: http://shop3.frys.com/product/5530040?site=sr:SEARCH:MAIN_RSLT_PG I have a $100 fry's gift card so I'd like to get it there.
