A:Answer Mine came with an ASROCK Phantom Gaming 4-CB, but you can end up with anything because they source out to whatever they have available, including custom boards that you'll NEVER get support for. Mine has the 2070, not TI, as well, and yes, there's an open slot, BUT, the config is so horrible that you'll end up with a toaster if you put two 2070's in there. They use Zotac reference cards, hamster wheel fan, and it gets HOT. In theory though, yes you can run two cards and they will fit. Power supply in mine is generic and is getting replaced. Again, it could be whatever they decide to put in it. Memory is ok, some off brand stuff, but i've already replaced it.
