This used to be <$500, but currently $633 for a motherboard, dual E5-2670 CPUs, and 128GB ECC memory: http://www.natex.us/Intel-S2600CP-Motherboard-Package-Deal-p...

Highly recommend this case if you go with an Intel S2600CP (or any other SSI EEB mobo): https://www.newegg.com/Product/Product.aspx?Item=N82E1681185...

I am using the Fractal Design Define XL R2 (what a name) for my Supermicro dual CPU mobo, I drilled one extra mounting hole and the mobo mounted just fine.

Very quite and solid.

+1 for natex. That's where I got my motherboard and it's worked great for about 6 months.
