I have the 7000X and converted mine to the 7000D, the X comes with a Commander Core XT, you can easily connect the node to it, it also has a fan controller. The case is one heavy beast when fully loaded. I'm getting ready to swap my Ryzen 5800x, Asus Prime x570 Pro, 32GB, H150i Elite Capellix AIO, and 3080 TI and put in a Ryzen R9 7950x, Asus Strix x670E-A Gaming Wifi and 32GB DDR5 6000, keeping the GPU, Cooler, drives and PSU. As for your fans the bigger 140s push a bit more air, but either way your fans will work. I took the cover off the side panel vent and left the mesh grill on it for a bit more air flow,
The main difference you'll notice between the X and D models is the X comes with the Commander Core XT and the LED fans the D model comes with fan controller and no RGB. I went the route of getting the X and then buying the airflow panels they have the same snap connectors on both models for all the panels. It's a good case, roomy, lots of tie downs on the back for cable management, just be warned if you use the alt bottom tray L shaped part, it has a gap on the side and if you don't tie your cables and tuck them away really well, they can pop out and ruin the look. The blue pic is the Ryzen R7 5800x
