12-bay 4U chassis for dense storage

This 19-inch rackmount server chassis holds twelve 3.5-inch hot-swap drive bays plus two internal 2.5-inch SSD positions. It accepts E-ATX motherboards up to 12 by 13 inches and provides eleven full-height PCIe slots for multi-GPU or accelerator cards. The 1.0 mm SGCC steel body with anti-fingerprint finish fits standard 19-inch racks.

12G SAS expander backplane under load

A 12 Gb/s SAS expander backplane with an onboard temperature-control chipset manages all twelve bays; a 6 Gb/s variant is available. Three 12038H ball-bearing fans and two rear 8038 fans pull air across the drives and the backplane, sustaining airflow during continuous GPU compute or rendering workloads. The CRPS power supply bracket supports redundant units up to 2000 W for steady delivery.

Tool-less drive trays and front I/O

Drive carriers slide into the front bays without tools, and the backplane connects each tray automatically. Two front USB 2.0 ports (USB 3.0 optional) give local access for media or diagnostics. Builders must verify motherboard height against the 176.5 mm chassis depth and ensure the chosen CRPS supply matches the rear bracket pin-out; the eleven PCIe slots are vertical, so full-length cards need rack depth clearance.

Questions about this item

How much heat and noise do the three 12038H ball-bearing fans and two 8038 rear fans produce during continuous operation?

The chassis includes three 12038H ball-bearing fans and two 8038 rear fans as standard; the backplane has a temperature-control chipset that adjusts fan speed to thermal load, reducing noise when drives are idle.

What motherboard and power supply must I already own to populate this empty 4U chassis?

You need an E-ATX motherboard no larger than 12 x 13 inches and a CRPS-form-factor power supply rated up to 2000 W; the chassis ships without either component.

Will my existing SAS drives and PCIe cards fit the 12Gb/s expander backplane and eleven full-height slots?

The 12Gb/s expander backplane accepts twelve 3.5-inch SAS drives and is backward-compatible with 6Gb/s drives; eleven full-height vertical PCI/PCIe slots support standard-length add-in cards.
