Pros: ATX board that supports 2 physical CPUs. That is a rare bird. I'm happy to report that the quality on this board appears to be top notch despite the lack of competition in this niche of the market. The manual is detailed, readable, and very thorough. Board has full length PCI-E slots which allows for use of a full size graphics card for those who wish to employ both high end CPU and GPU capabilities. Automatically detected and configured cpus and memory in a number of configurations including one cpu and two dimms, one cpu and four dimms, and two cpus with four dimms.

Cons: System takes about 60 seconds before it is ready to boot into an OS. Intel Genuine boot loader initializes twice before posting. One might be able to disable this feature in the BIOS but I haven't run across that section of the manual yet. I didn't take an egg off because it's not a big problem for a workstation or server that will likely run for a full work day or perhaps for longer sustained periods.

Overall Review: This is my first piece of truly professional level hardware. I had a little sticker shock but now that I've worked with it for a few days I am roundly impressed.

Pros: Good build quality ports are well spaced and easy to access Throughput for data and power are seamless Comes with a AC to DC converter 100W

Cons: Needs active HDMI to Display Port connection if you want to use more than one Display Port connection which requires a usb port for power.

Overall Review: Rosewill does it again and does it better than their more expensive competitors. The device does exactly what it says it does. What more can be said?

Pros: High quality Corsair power supply is a little redundant. Though it is refurbished and YMMV, the unit I received was pristine and functioned exactly as advertised. Has two CPU 8 pin power connectors for running dual physical cpus.

Cons: No documentation included. I'm not overly enthused by the lack of fan activity. I am running a pair of E5-2670s and, under stress, the power supply was quite hot to the touch and th efan was not running. It says clearly in the manual that is intentional but I worry about longevity and efficiency under that kind of heat.

Pros: 4 16GB ECC Registered DIMMS. Plugged into Z9PA-D8. System recognized and set the appropriate timings. Couldn't ask for more.

Cons: No scary looking heatsinks or overly bright LEDs.

I ordered $950 worth of refurbished CPUs and held my breath. I received a very well packaged and promptly shipped box via FedEx Ground that contained two pristine refurbished E5-2670s. What more could I ask for? Thanks for being awesome.
