ASUS Z8NA-D6C @ Motherboards.org

"ASUS is well known for their motherboards and the Z8NA-D6C fits the bill as a motherboard that can act as a server or a workstation with dual Xeon CPUs. While the cost of a Xeon system is expensive for the most high-end CPUs, there are Xeon CPUs like the 5504 that cost much less and when paired with a Z8NA-D6C motherboard provide a powerful computer for any server or workstation applications you need to run."
