Case server Chenbro 19" RM-238-12 2HE 12Gbps+ Exp. - case server - ATX

Data centers and IT integrators often need a dependable 2U rackmount chassis that balances storage density with flexible motherboard support. The Chenbro RM23812H01 delivers exactly that: twelve front-accessible 3.5" hot-swap drive bays with a 12Gb/s SAS/SATA expander backplane, ready for high-capacity storage servers, backup appliances, or virtualization nodes. Its steel construction and tool-less design simplify deployment in standard 19" racks, while the included 80mm hot-swap fans and optional redundant power supply support ensure continuous operation in demanding environments.

Why choose it

The RM23812H01 stands out for its 12Gb/s expander backplane, which allows all twelve drives to be managed through a single connection—reducing cable clutter and simplifying storage scalability. Its support for both ATX and E-ATX boards gives you flexibility in choosing server or workstation hardware, while the hot-swap fans and redundant PSU options minimize downtime during maintenance. Built from robust SGCC steel with a locking front bezel, it protects drives from unauthorized access in shared or colocation environments.

Ideal use cases

• High-capacity network-attached storage (NAS) or storage area network (SAN) nodes
• Backup and disaster recovery servers requiring large hot-swap drive arrays
• Virtualization hosts needing a balance of compute and storage in 2U
• Surveillance or media servers with high write-intensive workloads
• Custom appliance builds for software-defined storage or hyperconverged infrastructure

Good to know

The chassis operates reliably between 0°C and 40°C with 8% to 90% non-condensing humidity, making it suitable for most climate-controlled data centers. Optional tool-less rails (26") enable quick installation and servicing. Note that power supplies and rails are not included; choose compatible 2U CRPS units based on your redundancy and wattage requirements. The front bezel lock adds a physical security layer without impeding drive access when unlocked.
