I'm planning a new PC primarily for AI training and fine-tuning, and I'd appreciate recommendations for a case that can properly support these components: Ryzen 9 9950X3D, RTX 5090, 4TB Samsung 9100 Pro Gen 5 NVMe SSD, 128GB of 6000MHz CL30 memory, Arctic Liquid Freezer III Pro 360, and an MSI PRO X870E motherboard. My priorities are cooling, airflow, component clearance, and practicality rather than RGB or flashy aesthetics.

I’d look at Fractal Design for a performance-focused build. Their larger cases generally offer good airflow, practical layouts, and less emphasis on lighting. The Fractal Design Epoch XL would be a suitable full-tower option for oversized components and plenty of cooling.
Whatever case you choose, check the exact clearance specifications before buying. The RTX 5090 may be very large, and the Arctic 360mm radiator can be thick, so confirm GPU length, radiator placement, motherboard compatibility, and whether the radiator and graphics card can coexist without obstructing each other.
Corsair cases are worth considering if you want something simple and well built without being covered in RGB. Look for a model with strong front or bottom intake, enough room for the 360mm radiator, and clearance for a large graphics card.
Since you haven’t mentioned a specific style, there are quite a few good options. I’m partial to NZXT cases, especially the H7 and H9 lines. For a powerful build like this—particularly if it’ll sit on a desk—I’d lean toward the H9 for its space and airflow.
The system will mainly be used for AI training and fine-tuning, so cooling and sustained performance matter more to me than appearance.
I’m definitely more interested in airflow and thermals than aesthetics. RGB is actually something I’d prefer to avoid.
