Is anything not checked?

Fractal Design doesn't publish a height or thickness limit for the North, so those aren't checked.

Where do these numbers come from?

Fractal Design's published spec; card size from NVIDIA's spec page. Checked October 2026. Makers measure differently and connectors add a few millimetres, so treat a tight result as a reason to measure.
