A 1U server chassis with four hot-swap 2.5/3.5-inch bays, dual internal 2.5-inch slots, a 400W 80+ Gold supply and 12Gb/s SAS/SATA backplane
This 1U short-depth chassis supports four 2.5 or 3.5-inch hot-swap drives on a 12Gb/s SAS 3.0 and SATA 3 backplane. It includes a 400W 80+ Gold power supply and two internal 2.5-inch drive bays. Two easy-swap 40 x 28mm PWM fans with anti-vibration mounts provide cooling. A built-in info-tag assists with system management.
Suits deployments needing dense front-access storage in a shallow rack footprint with redundant-class cooling fans. The four hot-swap trays accept both 2.5 and 3.5-inch SAS or SATA drives. Builds requiring PCIe expansion slots for add-in cards or GPU support should consider other platforms. The fixed 400W power supply limits high-wattage CPU configurations.
The Mini-SAS HD backplane runs at 12Gb/s and handles SAS 3.0 and SATA 3 protocols for the four hot-swap bays. This single spec decides if the chassis matches your drive topology and controller speed. Verify your RAID card or HBA supports 12Gb/s Mini-SAS HD connectors before purchase.

Mount the chassis, connect the Mini-SAS HD cables to the backplane and route them to your RAID card or motherboard; the step often missed is seating each drive tray fully until the lock clicks so the 12Gb/s SAS 3.0 link trains correctly.
The 40 x 28mm PWM fans are easy-swap; remove the anti-vibration pins, pull the fan module out and replace it without tools when bearings wear or airflow drops.
The 400W 80+ Gold unit sets the power ceiling; continuous draw near 400W will hit the supply limit before thermal or backplane bandwidth constraints appear.
