Hi! Here is my "cheater" build for the Fractal Terra case:

Components 
Case: Fractal Design Terra
CPU: AMD Ryzen 7 7800x3d
GPU: RTX4080SUPER with Bykski water block
PSU: Corsair SF1000, 1kW
Mainboard: Asus Rog Strix B650E-I Gaming Wifi
Sound Card: ESI MAYA44ex
External Cooler: Mo-Ra IV 400

I designed and 3d printed a carrier for the sound card, which is now piggybacking on the water block of the GPU. It is connected to the Mainboard via a M.2 breakout cable and M.2 to PCIe-adapter.
I get 1ms latency in Guitar Rig 7.

The water cooler is controlled and powered by the mainboard via a breakout module, which connects to the PSU and the pwm outputs of the cpu fan and aio connectors on the mainboard.

The whole setup is entirely inaudible even under full load (like rendering in Blender3d).

Edit: corrected a typo: it's a 4080Super, not a 5080
