So, I'm looking to setup a Mini as a iTunes and Time Machine server for the 2 MacBooks, 1 ATV2 and 2 iPhones in my place. I'll handle the storage needs through a combination of ethernet and firewire, so the internal storage doesn't need to be much of anything. Aside from upgrading the ram, what else would I need in a system like this? I tend to think that picking up an older Mini would be less expensive although I'm not opposed to a 2011 base model and grabbing the $50 Server upgrade from the App Store. I'm open to any and all suggestions, and thanks in advance for your input.
