PCStats seems to have the first production motherboard reviewed based on the NVIDIA nForce4 SLI Intel Edition chipset. 

The physical layout of the Gigabyte GA-8N-SLI Royal motherboard is excellent but we’ve come to expect that from Gigabyte. It’s nice to see that Gigabyte includes everything end users would need with the motherboard as well, why can’t more manufacturers follow Gigabyte’s lead? A note to those who want a nForce4-SLI powered Intel computer: You’d better have good case cooling since the Crush 19 and MCP04 chipsets get quite hot during operation!
