Mine is a "Poor Man's" special.
* Asus A8N-SLI Premium Motherboard (4 Sata II ports on PCIe, 4 Sata I ports on PCI. Great board for unRAID as you can easliy get 17 ports on the PCIe bus & you get Gigabyte ethernet on the PCIe bus using the built-in nVidia. The only negative is you need a graphics card thus the reason I grade it an A instead of an A+)
