That sucks about HDMI.  Next time I buy a video card, I need to get one
with display port outputs.  It seems more Linux friendly.  :-D

I got the X model.  It's supposed to be a wiiiittttttle bit faster.  o_O

I was hoping so.  Doing that by hand would take a LOT of time.  I never
could figure out vim.  I use nano on command line and Kwrite in a GUI. 
Care to guess which I really prefer???  LOL 

I got the little m.2 thing today.  It's a lot smaller than I expected. 
A whole lot smaller.  It's fairly tiny actually.  They look bigger in
pictures or on video.  This reminds me of the discussion on the number
of transistors on a chip.  I bet they packed tight in there.  I bought a
heat sink that goes on each individual chip, one on controller, one on
data chip, two if it has two data chips.  Anyway, it has only two chips
so I got extra heat sinks.  LOL  They fairly large since the mobo has
nothing on top of them.  I got plenty of room.  That said, anyone else
notice they make heat sinks for those things that have heat pipes and
itty bitty fans??  O_O  It does make them run cool tho.  :/  I like my
little heat sinks better.  Pretty good size and no moving parts.  They
come in a couple colors.  Linky.

Oh, for those reading this.  The data controller chip is a little
thinner than the data chip.  I confirmed that on mine.  If you don't use
a heatsink that has a thicker pad for that, it leaves a gap and the
controller chip doesn't make contact which means it runs hotter.  As I
mentioned earlier, the controller seems to produce more heat so it needs
the heatsink more than the data chip.  On videos, some people use a
additional pad to make up the difference on the controller chip.  I
noticed on a couple heatsinks, they mention the difference and show they
use a pad that makes full contact on both chips.  It looks like the
thermal pad is thicker and more squishy.  One I saw looks like it is
just a little thicker on the controller end. 

I guess Monday will be the big day, IF, big IF, they don't get hung up
in the local USPS sorting hub.  That place is a little better now but
some packages still get hung up down there.
