wowza, 12 hard drives? You suuuuuuure you wanna go WHS on that? Both of those other server platforms I mentioned would be much slicker with that many drives. But as you said, setting up WHS is a snap…but hey, you could always just try FreeNAS out for example and if you don’t like it, then go the WHS route (before you start copying stuff over and then can never go back)
