Server chassis Supermicro SuperChassis 216BE1C4-R1K23LPB Rack Black

The Supermicro SuperChassis 216BE1C4-R1K23LPB Rack Black is a 1U rack-mount server chassis engineered for dense 2.5" drive deployments and enterprise rack environments. Designed to accept EATX and ATX motherboards, this compact chassis provides 24 internal 2.5" drive bays, an integrated 1200 W power supply with wide AC input support (100–240 V), and a low-profile 89 mm height suitable for standard server racks. Its black finish and efficient footprint make it appropriate for data centers and network closets where space efficiency and drive density are priorities.

Advantages

The chassis offers high drive density in a 1U form factor, enabling storage-dense configurations without increasing rack space. The included 1200 W power supply supports stable operation across a broad AC input range, reducing the need for immediate PSU upgrades. Compatibility with EATX and ATX motherboards allows flexibility in system design and component selection. The 24 front-access 2.5" bays simplify drive installation and replacement, facilitating maintenance in managed environments.

Suitable for

• High-density storage servers and NVMe/SATA drive arrays
• Virtualization hosts or hyperconverged infrastructure needing compact rack footprint
• Backup appliance or archival storage systems with many small form-factor drives
• Enterprise edge and colocation racks where rack units are limited

Key specifications

• Form factor: 1U rack
• Supported motherboard form factors: EATX, ATX
• Drive bays: 24 × 2.5" internal
• Power supply: Integrated 1200 W, AC input 100–240 V
• External dimensions (W×D×H): 437 mm × 630 mm × 89 mm
• Color: Black
• Front-access drive layout for tool-less or tray-based 2.5" drives (dependent on drive carriers)

How to use

Install a compatible ATX or EATX motherboard using the standard standoff pattern, then populate the 24 internal 2.5" bays with drives using the appropriate carriers or trays. Connect the integrated 1200 W power supply to the motherboard and drives using the system power connectors and ensure the AC input falls within the 100–240 V range. Mount the chassis into a 19" server rack using standard rack rails or brackets, secure it in place, and connect network and peripheral cabling as required. Follow server vendor guidance for cooling, drive configuration, and RAID or controller setup.

Recommendations

For optimal thermal performance, deploy the chassis in a rack with adequate airflow and ensure drive carrier airflow paths are unobstructed. Use matched drive types and a compatible backplane or controller to simplify management. Verify power and cooling capacity at rack level when operating many populated units to maintain reliability.
