I wonder how many SATA ports, Ultra M.2 slots, and PCI-E x16 slots can be used at once before they start disabling themselves or drastically dropping speed.  To me, it seems like this will create a very complicated setup experience for the user when the user needs to consider all the caveats and restrictions.

And I thought the X79 Extreme11 was overkill.  Looks like they're taking it a step further with this one.  They're amazing to read about, but they have way more than I need.
