Is anything not checked?

Lian Li doesn't publish a height limit for the Q58, so that isn't checked.

Where do these numbers come from?

Lian Li'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.
