Corsair FRAME 4000D
The 4000D's modular successor, the FRAME 4000D adds InfiniRail adjustable fan mounts, expanded 430mm GPU clearance, and support for BTF/reverse-connector motherboards, with radiator room up to 360mm on front, top and side. Its beginner tier reflects approachable pricing rather than limited capability. A strong, future-minded foundation; just note it tops out at 360mm radiators and ships light on included fans.
