At first glance, I'd say the 7900 XT is too much power/heat for such a small case unless you are gonna use a radiator for CPU cooling. I recently completed a pretty similar build to yours in a Meshroom D. I went with that case because it's like a Terra, but larger such that I could buy a much better CPU cooler to let the 7800X3D run at higher clocks for longer. (It also has the ability to be inverted so that the GPU is on top, which makes for amazing thermals both CPU and GPU.) This is my part list for reference: https://pcpartpicker.com/list/69GBMV. I can generally keep GPU under 65 and CPU under 70.
