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.
