Corsair Frame 4000D vs Phanteks P400A: Comparison
What is the difference between Corsair Frame 4000D and Phanteks P400A?
Start with included fans, because it is the widest measured gap between them: Corsair Frame 4000D 2 against Phanteks P400A 3, 33% in favour of Phanteks P400A. Add gpu clearance to that, 360 mm on the Corsair Frame 4000D versus 420 mm on the Phanteks P400A, and the pattern holds.
Which should you buy, Corsair Frame 4000D or Phanteks P400A?
The Corsair Frame 4000D suits builders who want to change the case's aesthetic later and standard ATX gaming builds wanting 360mm front radiator room, though it is the wrong buy for budget builds where the panel kits aren't worth the premium and builders who already know exactly which panel style they want. The Phanteks P400A is the one to take for budget builds where front USB-C isn't a requirement and large GPU builds needing 420mm of clearance, though it is not the pick for anyone who needs front-panel USB-C and large air coolers over 160mm tall. 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. Our rating of the Phanteks P400A (7/10): A dated but still capable budget mesh case; worth buying only if it's discounted below current-generation alternatives like the XT Pro.
