I currently have a Mac Pro and MacBook pro and I'm thinking of getting a Mac mini server to use primarily for a central iTunes/storage. I don't like having to run my Mac Pro all the time in order to stream content to my AppleTV. I also plan to use it with my home automation software (so the low power consumption is a plus). I plan on putting it in the closet with my network storage where it will be accessed only remotely from my MacBook (Im not interested in another display and keyboard setup), therefore the graphics part of the mini is really irrelevant for me. I will continue to rip and encode on the Mac pro and then transfer the files to the mini/NAS. That said, is there any reason I should pay for the server model or just get the basic mini and download the server software for $50 (plus drop an extra 2GB ram in there)?
