Is anything not checked?

Sliger doesn't publish a thickness limit for the Cerberus, so that isn't checked.

Where do these numbers come from?

Sliger'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.
