Pros: It does turn on. It is somewhat useable.

Cons: There's some type of ACPI issue with this motherboard that doesn't allow using it as a Xen Dom0 or FreeNAS box - neither will boot at all. You can get it to boot a vanilla Linux kernel, just boot with acpi=off. Furthermore, I updated the bios in the hopes the above ACPI issue would be fixed. It isn't. And in addition to that issue not being fixed, I can no longer boot from a USB device after the update. This thing is a piece of trash. I'd return it if I hadn't spent so much time trying to trouble shoot it and install all the components. It's working well enough, and since I don't have time to play around with RMAs and walk around in circles at the post office, I'll look forward to it's death (which will probably happen soon enough anyway) and I'll be on the search for an online components retailer who actually stand behind the products they sell.
