The 400R / 500R has been carefully designed to provide a generous amount of internal volume, and it puts that volume to good use. There’s room for eight PCI-E cards of up to 316mm in length, and even room for a full 240mm radiator for compatibility with the Hydro Series H100 Liquid CPU Cooler and modular watercooling systems. Superior airflow is a requirement for high-performance components that will be regularly pushed to their limits, so the 400R has ten fan mounting points for cooling flexibility. Three 120mm fans — two in the front, and one in the rear — are included, so you’re ready to start building right out of the box.

Carbide 500R: Serious airflow never looked this good.

Want even more outrageous cooling flexibility? Step up to the 500R. It adds a 200mm fan mounted on the side panel’s mesh screen for extra GPU cooling, a multi-channel fan controller, and removable and relocateable hard drive cages. The ability to move and remove hard drive cages not only improves airflow — it also allows you to install graphics cards of up to 452mm in length.
