I got one of these boards about a week ago and are performing some tests right now.
What I can say for sure is that it's "only" an 8-SATA board. 6SATA on the ICH-10 chipset and 2 (usable) on the JMB323 chip.
LAN-ports are working great. USB-boot works.
My build will run unRAID together with vm-ware so my specs are perhaps a bit high, but here they are:
Mainboard: GA-EP45-DQ6
CPU: Intel C2D E8600
Mem: 4x2GB DDR2
SATA-controller: Adaptec-1430SA (PCIe x4)
Case: Norco-4020
Drives: 10x500GB WD RE2-GP + 1x1TB WD Black as cache-drive (hosting VM-ware)
