Very much like what I'm doing with my LSI board providing most of my
data storage, with boot disks (mirrored) on the MB SATA ports.  Makes
for a simpler setup.

This is a nice idea, just not sure I want to go with 2.5" drives since
they're expensive per TB of storage.  I just want one of those old
style monster cases with 8 x 5.25" bays so I can fill it with 3.5"
bays.  Or there was a review on Phoronix.com about a 4U chassis that
looked pretty good, esp with USB3 front ports.
