I am upgrading my current network to (potentially) remove my windows 2003 server box. I do not really need the server features and will just run OSX and not OSX Server. I have switched to all Apple systems now and want to have one central computer that will always be on which will manage a centralized iTunes, iPhoto, etc etc libraries on external hard drives and also act as the backup for the other computers. I will also have Apple TV's attached. I was thinking of going mini for this and then thought, once I get screen, keyboard, mouse, should I rather just go macbook or imac for a little more. If possible, pros and cons of each.
