Hi Higgins12,
I've been following this forum for a few weeks now, and recently signed up. I purchased an i9-9900K shortly after and have been gathering information for my build, which I'll mention elsewhere...
I believe, from what I've been reading (from every corner of the Internet) is that you have successfully fixed all of your remaining issues/action items for a complete and working build using a new z390 board that is actually a regular sized ATX form factor. I have a hard requirement of needing more than a single x16 so that I can get in more than one card for my Linux and BSD tri-booting. I literally couldn't pull the trigger on a motherboard until I read that someone actually fixed all of the issues they are having with a new board. The board you chose also has everything one should need:
1xDP, 1xHDMI, BT5, TB, Wifi, and even 10gigE!
Can you please create an official user build, following:

All of my parts should be arriving over the weekend and early next week. I just pulled the trigger on the
Asrock Taichi Ultimate z390 after reading this post, which was the last piece I was missing... I'm super excited!
Cheers!
