So I'm about to start consolidating my live music collection to hard drives. I'd like to use RAID to serve my stuff. Everything will be in 16 and 24 bit FLAC running off of my old Titanium Powerbook. I'd like to pickup a 5 drive RAID box that connects over USB 2 or Firewire 800 (so I can add another in a daisy chain in a few months), for around $1600. Any suggestions are welcome. Also, if anyone knows a program similar to itunes for OS X that can handle FLAC, I'd love to hear about it. Thanks.
