This is a nice NAS build motherboard, with onboard SAS2308 that can easily be flashed with IT mode firmware.

The board layout and PCIe slots are not great for long PCIe cards or GPUs; so not a good choice for a workstation. Rev in the photos appear to be 1.02, which should support Ivy Bridge v2 CPUs; but might want to confirm with seller that you will get a rev 1.02.
I don't know this seller, but my only hesitation is the seller: the photos show one of the heatsinks (that will be included) installed backwards; indicating that their technicians may not know what they are doing. And secondly, the seller has a few negative feedbacks indicating similarly, so YMMV with this seller. BUT, the price is really nice so might be worth the risk and you have buyer protection.
