Minor mistake in the review, otherwise good work : this board actually DOES feature Nvidia SoundStorm! Written on the back of the box in fairly big letters (doh) plus deatiled on the DFI spec page.

If you want 5.1 audio out then you must scarifice the mic-in and line-in ports since the IO plate only has 3 audio jacks. However, a rear backplate bracket is available direct from DFI to add extra audio jacks which will prevent the loss of those ports (but it's NOT included by default in the box, which would have been better to see).
