quest for a mainboard (2)

I started looking at the mainboards with builtin videocard, but then I noticed none of them have more than 4 SATA ports. And I need atleast 5, preferably 6 (5 for the RAID and 1 for the /)

Looking at the SATA ports, there are 2 with 8 ports, 2 with 6 and 1 with 5.
Both mainboards with 8 ports don't actually have 8 ports but only 4, I was wrong :(

The choice is between these motherboards:
Asus A8N32-SLI Deluxe
MSI K8N-Diamond-54G
MSI K8N Diamond Plus
