Much appreciated!  So now that I'm squared away on that important bit of info, there is a small complication.  More than likely, I'll have to plug the M.2 into the second available slot as the first slot has both the GPU and a giant CPU cooler nearby.  Now, I'm hoping that the second M.2 slot is a twin and I would loose no functionality by plugging into it.  Again, thanks so much for your help so far wONKEyeYEs.
 
Cheers
 
Edit:  I just realized my mistake by looking at the graph again.  Answered my question. 

Yes, it looks like if you put your sata m.2 in the M2_1 slot for example 
you will have sata ports 3, 4, 5, and 6 available.
