Gpu clearance is closer, 375 mm on the Antec P20C versus 360 mm on the Corsair Frame 4000D. They differ on radiator support too, Front up to 360mm, top up to 360mm, rear... on the Antec P20C versus Front 360mm, Top 360mm on the Corsair Frame 4000D.

Which should you buy, Antec P20C or Corsair Frame 4000D?
The Antec P20C suits tight-budget builds and airflow-first builds under $600 total, though it is the wrong buy for E-ATX motherboards and showcase RGB aesthetics. Buy the Corsair Frame 4000D for builders who want to change the case's aesthetic later and standard ATX gaming builds wanting 360mm front radiator room, though it is not built for budget builds where the panel kits aren't worth the premium and builders who already know exactly which panel style they want. Our rating of the Antec P20C (7.5/10): the cheapest genuinely good mesh airflow case in our catalog, no meaningful corners cut for the price. Our rating of the Corsair Frame 4000D (7.5/10): A smart idea for anyone who isn't sure whether they want mesh or glass yet, though it's a premium over the regular 4000D Airflow for the same base performance.
