Hopefully this is the right forum for the question. I am looking for some advice on setting up a file server in my home. I am an "almost" exclusively Mac home with 2 higher end PC's that are strictly for gaming. The other machines are MacPro1,1, 2 X iMacs, 4 X Macbooks, 2 X iPads, and various iPhones/iPods. Current Situation Server MacPro2,1 8-core 16GB Memory 120GB Boot SSD, 3 X 2TB WD Green, 1 X 1TB WD Black. Attached to this is an external 2TB FW800 drive for Time Machine on the MacPro and critical data. Also attached is an eSATA 4 bay array with 3 X 2TB WD Green (Movies) and a 500GB (Home Videos). The Movie disks are backed up to matching disks that I keep separate from the machine and use SuperDuper to update occasionally in my eSATA disk dock. So I have 6 X 2TB drives and a 500GB drive for movies. Back when I was ripping my entire collection from DVD's to DVD images plus MP4's the mac pro 8 cores came in really handy with Handbrake. But now that the collection is done I am only adding new material infrequently so I have this huge powerhouse machine acting as a glorified file server 99% of the time. I am looking for a more power efficient solution now and free up the MacPro to someone who can better utilize its power. I currently have a 21.5" iMac Core2Duo but am considering replacing this with a 27" i7 quad core that would allow me to still do the odd Handbrake run relatively quickly. That would remove any requirements I have for keeping the Mac Pro. Options 1) Get a Mac Mini and modify it with an eSATA so I can re-use my external 4 bay array. Use the Firwire port to attach the external FW Time Machine disk and possibly get a FW800 enabled 4 bay enclosure to round out the full disk storage I currently have. 2) Drobo FS. Add 5 X 2TB drives. I no longer need drives for OS X so it would be strictly Movies and critical files. I could always add more drives to my Airport Extreme Router which currently hosts a 2TB drive for Time Machine for the rest of the Macs in my home. 3) Other ideas?
