Is anything not checked?

HYTE doesn't publish a height limit for the Y40, so that isn't checked.

Where do these numbers come from?

HYTE'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.
