## Long description

The Silverstone RM400 Rack Black is a rack-style server case designed for compact server installations and storage-dense systems. The chassis supports ATX and smaller motherboard form factors, accepts both ATX and PS2 power supplies, and provides multiple front drive bay options for 2.5", 3.5" and 5.25" devices. The RM400 integrates one rear 80mm fan and allows front fan configurations in either 80mm or 120mm sizes to help maintain airflow in a shallow-depth rack footprint. With a steel SGCC construction and a two-tone grey and black finish, the case targets small rack deployments and workstation cabinets where efficient cooling and accessible drive capacity are required.
Advantages
The RM400 offers a balance of compact dimensions and high drive density, fitting eight 3.5" bays alongside additional 2.5" and 5.25" bays while remaining suitable for standard ATX power supplies. Its SGCC steel construction provides structural rigidity for rack mounting and repeated access. Front I/O includes two USB 3.2 Gen 1 Type-A ports for direct connections, and the configurable front fan options permit users to prioritize airflow or quieter operation depending on installed fans. The preinstalled 80mm rear fan contributes to baseline ventilation out of the box.
Suitable for
 Compact rack-mounted file servers and NAS systems
 Small office or lab servers requiring multiple 3.5" drives
 Backup and archival storage with mixed 2.5" and 3.5" drives
 Workstation-in-rack setups using ATX or smaller motherboards

How to use
Install an appropriate motherboard matching the supported form factors, then mount the power supply of the chosen type (ATX or PS2) in the designated bay. Populate drive cages with 3.5" or 2.5" drives using the supplied mounting points and secure any 5.25" devices in the front bays. Connect front-panel USB ports to the motherboard header and route power and data cables to drives and the motherboard with care to preserve airflow. Configure front fans in either the 80mm or 120mm positions according to your cooling needs, and verify the included rear 80mm fan orientation for exhaust.
Usage recommendations
For optimal thermal performance in rack environments, use a combination of front intake fans (120mm where possible) and the rear 80mm fan as exhaust, maintain clear front-to-rear airflow paths by tidy cable routing, and choose drive models appropriate to workload and vibration tolerance. Ensure the selected power supply provides sufficient wattage and has the required connectors for drives and motherboard. When installing in a dense rack, allow front clearance for intake and consider using vibration dampers for high-capacity mechanical drives.
