How about an ASRock 4X4 BOX-4800U instead?  On the minus side the two realteks are a bother but since the target is a desktop this is less of an issue given that on the plus side it is capable of producing 16 penguins on bootup.  From my perspective the 16 penguins trumps the realteks and perhaps will convince the realteks to behave themselves.

Also it is quad monitor capable and is reasonably priced.  If I had to decide today this one would be the winner.

Life is good,
