Is anything not checked?

NZXT doesn't publish a height or thickness limit for the H5 Flow, so those aren't checked.

Where do these numbers come from?

NZXT's published spec; card size from PowerColor'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.
