I wasn't talking about boards in stock, I checked Asus, Gigabyte, MSI and Asrock and Asrock is the only one that is actually making a matx x570 board. There are itx boards from Gigabyte, Asus and Asrock.
Good luck actually finding one of the 2070 itx cards, when Nvidia brought out the Super they discontinued the non Super versions so both the Gigabyte and MSI are impossible to find anymore. MSI has a product page for a RTX 2060 Super Aero itx although I haven't seen it for sale anywhere yet.
The sleeved cables included with the Platinum will be better than the flat cables included with the Gold, you will still have very long cables for the MI-6. I found custom cables just made things so much easier to build in the MI-6.
