Keep in mind all the "keys" you have to buy to enable built-in functionality.

Summary: Once you get all the "optional" "keys" to unlock Trusted Platform, Raid capability, all SATA port capability, your price is way up over an equivalent SuperMicro board with more functionality. Also check that your first PCIe card is 6" or shorter as the memory placement interferes with it.
