4U Rackmount Chassis for High-Density Storage

The Rosewill RSV-L4000U is a 4U rackmount server chassis built for environments that need dense hard-drive capacity. It accepts up to eight internal 3.5-inch drives and three external 5.25-inch devices. Motherboard support covers ATX, E-ATX, Micro ATX and Mini ITX form factors. This makes it suited for home servers, backup appliances or small business storage arrays.

Installation Notes and Common Issues

The chassis ships with seven pre-installed fans: two 120mm units at the front, three 120mm units in the middle and two 80mm units at the rear. Middle fans must be removed to fit graphics cards longer than 320mm, with a maximum length of 400mm without them. CPU cooler clearance is 117mm with the GPU holder installed and 152mm without it. The SGCC steel construction weighs 13.80kg, so rack rails rated for the load are required.

Pre-Purchase Compatibility Checks

Verify that your rack provides at least 4U of vertical space and a depth of 635mm for the chassis body. Confirm your power supply does not exceed 220mm in length for standard ATX or mini-redundant units. Ensure the motherboard I/O shield aligns with the seven expansion slots provided. Front-panel connectivity is limited to two USB 3.0 ports and LED indicators for power, drive activity and two LAN links.
