Mac Mini 2014 hard drives Do the Mini 2014 mechanical hard-drive versions have an M.2 ssd slot on their mainboard? 

EDIT: Let me clarify: the fusion version have a M.2 SSD on the mainboard slot and a 2.5" mechanical drive. Will I find this M.2 slot even on the mechanical-only version?

I'm referring to both 1.4 and 2.6 GHz versions.

Thanks.
I think no, as reported here in this guide for replacing the SSD only the SSD or Fusion Drive version has the M.2 slot:

By the way you can easily figure out this opening the enclosure on the bottom following the guide linked before.
