The Rosewill RSV-Cage is a four-drive 3.5-inch HDD add-on module for Rosewill RSV-R4000 and RSV-L4000 chassis, suited to owners of those cases who need additional drive bays; it includes a 120 mm fan.
Recommended For
- Home-server and NAS builders with a Rosewill RSV-R4000 or RSV-L4000 who want to add four 3.5-inch drives without replacing the chassis; the manual describes the cage as expanding these cases from 8 to 12 hard drives.
- Data-hoarding and backup-server builders who have three available 5.25-inch bays in a compatible chassis and want to use that space for four additional 3.5-inch hard drives.
- Owners expanding a multi-drive homelab server who are comfortable installing an internal cage and managing drive and power cables; community builds document converting RSV-L4000 systems to higher-capacity storage setups.
