- 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 ASUS'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.
