Is anything not checked?

Lian Li doesn't publish a height or thickness limit for the O11 Dynamic EVO, so those aren't checked.

Where do these numbers come from?

Lian Li'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.
