Is anything not checked?

Lian Li doesn't publish a height limit for the A4-H2O, so that isn't checked until we measure the case ourselves.

Where do these numbers come from?

Lian Li's published spec, not yet measured by Respec; card size from PNY'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.
