Antec P20C vs Phanteks P400A: Comparison
Antec P20C vs Phanteks P400A: the gpu clearance difference
The gap that matters here is gpu clearance: Antec P20C 375 mm against Phanteks P400A 420 mm, which puts Phanteks P400A 11% ahead. On cpu cooler clearance there is little in it, 170 mm on the Antec P20C versus 160 mm on the Phanteks P400A. Radiator support is not the same on both, Front up to 360mm, top up to 360mm, rear... on the Antec P20C versus Front 360mm, Top 240mm on the Phanteks P400A. They differ on panel type too, Tempered glass side, mesh front on the Antec P20C versus Mesh front panel, tempered glass side on the Phanteks P400A. There is a split on front usb-c as well, Yes on the Antec P20C versus No on the Phanteks P400A.
Who each one is for
The Antec P20C suits tight-budget builds and airflow-first builds under $600 total, though it is not built for E-ATX motherboards and showcase RGB aesthetics. Buy the Phanteks P400A 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 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 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.
