Rackmount chassis with 12 NVME bays

This 1U rackmount server chassis holds up to twelve 2.5 inch NVME U.2 or Mini SAS HD drives in hot-swap carriers. It accepts motherboards from Mini-ITX through E-ATX up to 12 by 13 inches. Six 40mm fans provide front-to-rear cooling. The steel frame includes a metal keylock for physical security.

Suited for dense NVME storage nodes

Buyers building all-flash arrays or high-density storage servers will use the twelve-bay backplane and E-ATX board support. It is not for workloads that need multiple PCIe add-in cards, as only one expansion slot is available. It is not for 3.5 inch drive deployments or for towers that lack 1U rack rails.

Single expansion slot limits add-in cards

The chassis provides exactly one low-profile expansion slot, so only one controller, NIC or accelerator can be installed. Every other specification depends on the motherboard and power supply chosen separately. Verify that your selected board and 1U redundant, single or FlexATX PSU fit within the 18 by 1.75 by 25 inch envelope.

Questions about this item

How many NVME U.2 drives can the 12-port backplane support at once?

The backplane supports up to 12 hot-swappable 2.5" NVME U.2 drives with a 15mm height limit.

What cooling noise and airflow should I expect from the six 40mm fans running continuously?

Six 40mm high-CFM central fans provide forced airflow; noise level is typical for dense 1U server chassis under sustained load.

Which power supply form factors fit this chassis so I can power it up?

Compatible with 1U redundant, 1U single, or FlexATX power supplies.
