Is anything not checked?

Jonsbo doesn't publish a height or thickness limit for the Z20, so those aren't checked.

Where do these numbers come from?

Jonsbo's published spec; card size from Gigabyte'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.
