The 670 has 2 SATA connectors on the mobo as well as well as the onboard
SCSI.  I'd prefer to not use the inbuilt hardware raid.  My current
desktop has a single 80GB IDE for /, /boot, swap etc and a pair of 300GB
SATAs for /home (Raid 1 on /dev/md0) on the basis that my data is more
important than the OS.  That's worked fine for about 3 years so plan to
use same strategy now.  Basically don't want /, /boot on a raid hence
keeping the SCSI for that.
