Thanks everyone for the advice, here's my plan at the moment:

1) install the OS only on the 2 500GB drives (in a RAID 1 config)

2) then once it's up and running use something like gdisk to create the 
4TB partitions...

Question, can someone point me to a how to per taking the 6 4TB drives 
and doing the following once they are all partitioned:

- set each drive as a raid partition
- create a single RAID 10 device from the partitions
- have the volume auto mount (via fstab?) at boot time


Thanks in advance
