I'm about to build a home office server and need some tips to get started.
Here is what I have and what I want to do:
My wife and I both have mac book pros. Connected to each is a USB drive used for time machine and one or two firewire drives with work related files and archives.
Somewhat separate from this is my monster gaming PC. Its great for playing Metro 2033, but serious overkill for streaming itunes to the apple tv. It has 4-1.5TB drives in raid 0+1. All of my movies are also stored here.
What I would like to do is build a device that stores all of this and gets rid of all the external drives. It would need a place for time machine backups, places to keep all of my work related files and archives, places for music and movies. I would also like it to run itunes 24/7 so when I want to watch a movie on the apple tv I don't have to turn on the big water-cooled monster. I would still use the big PC for transcoding videos but then load them into itunes on the new server.
I think 6TB is enough to start, but I'd want to expand to 12 pretty quickly.
I'd like to leave it on 24/7 and only connect a monitor to it if there was a major problem.
Low power and very quiet are important

I don't think speed is a huge concern, but 50MB/s writing would be nice.
