I was just given a Dell R720xd with 160 GB memory and 12x 900 GB drives 
that I plan to deploy as my home mail/file/backup server to replace an 
aging Supermicro server running CentOS 7. Yeah, it's gross overkill for 
that and I expect to tuck most of the drives away for spares.

How should I RAID and partition this beast for maximum reliability?

My current C7 system is using 1 TB of 2 TB capacity on the root partition 
(4x 1 TB drives in RAID 10). /boot is 300MB/50GB. Memory and swap is 8GB
