The Corsair Frame 4000D RS ARGB InfiniRail system eliminates fixed mounting holes, letting you slide fans along a steel rail to position them exactly where your build needs airflow most. Install up to two 360mm radiators at once across three available locations: front, top, or side panel. Compatible with the latest reverse-connector motherboards that relocate all power and data cables to the back side of the board. This case is ideal for users who need substantial cooling capacity but want to minimize noise.
