I'm looking to create a setup that allows me to have my torrents seeding, my itunes library, and time machine backups for whoever is using a mac in the home. I'm essentially ruling out using FreeNAS with AFP shares on a cheap CPU/mobo, that would be nice but also means that any streaming to an Apple TV would go from Apple TV -> router -> my mac -> router -> NAS -> drive -> NAS -> router -> my mac -> router -> Apple TV. Ideally, it seems like I'd use a Mac Mini with a 4 bay drive attachment. That way I can also use it as a a video conversion hub and an iTunes server without having to leave my laptop open. My understanding is Firewire 800 is the best way to drive enclosures (besides eSATA, but that obviously isn't an option). Also, I want at least 4 bays, and I already have a 500 gb external from Western Digital that runs on PATA. Basically, what I'm wondering is how to get all this working. I can't find *any* enclosure for four drives that uses firewire, and some expensive ones (150-200) for USB 2. It looks like I won't be able to put the PATA drive in a SATA enclosure. It's looking like right now that my best bet is getting a mini, then hooking up a USB hub that routes to cheap enclosures for each separate drive, so then my storage space is essentially unlimited in the future. Also, what is the best way to keep backups in case of a crash? Just use Time Machine to backup at least my iTunes library so I don't lose that, and probably not the torrents since they take up so much space? Comments, suggestions?
