The zfs question is one I'm debating. I actually already use FreeNAS on the backup server and it seems to be doing well. For the primary server I want an OS I can do more with on, so I'd probably throw something like CentOS on it and then run VMs for specific tasks or to use more bleeding edge distributions. I suppose I could try zfs in Linux.
