"...For Win 10 you need a 2012 or later Mini (Macmini6.1 or later)..."
FWIW, Win10/1809 runs very well on a 2011 Mini Server. The issue is it
will not "directly" install and needs Win7 first then upgrade to Win10.
It seems there is some platform driver in Win7 that gets grandfathered
into Win10.
Just thought I would make you aware of this. Actually, the process works
with a 2010 Mini as well, although some manual install of some drivers
once in Win10 is required. But then it is Windows, so drivers tend to always
be an adventure on any computer.
