I've read a bunch of threads about options for the Mac Mini -- SSD, PcIE, 2x, 4x SATA SSD, blades -- I don't really understand it all. I'm planning to get the $699 Mac Mini. I thought I read somewhere that it's possible to buy one without any internal storage, and then use the savings to buy an internal SSD -- all in for the same $699. Is this possible? Assuming that's not really possible . . . What are my options for a good internal SSD that will sit on top of the internal 1TB hdd? I plan to use the Mini primarily as a music server. My thought is to put the OS on the SSD, and probably my server software (JRiver, I think), and leave the music files on the HDD. Thanks in advance.
