I don;t think there is one like that yet, or even planned.
If you want a Dual CPU system look at the AMD Athlon MP with a AMD 760MPX chipset. It does have DDR ram without SCSI. This system will either keep up or be faster than a Xeon system, and be cheaper.
Look at the frontpage of Anandtech. They did a test with the Xeon and the Athlon MP and found ther Athlon MP system to be a better buy. This board is being run by those systems, Athlon MP, right now.
Also I just got done building a Dual 1Ghz Duron computer with the 760MPX chipset. Very fast and Stable.
