Why choose it

The UNC-409S-B-OP stands out for its short depth without sacrificing ATX compatibility. The 1.2 mm steel construction ensures long-term durability in demanding environments, while the included 400 W power supply reduces build cost and complexity. Tool-less drive bays and removable dust filters simplify maintenance, and the lockable front door adds physical security for drives and controls.

Ideal use cases

• Compact server or workstation builds in shallow racks (network closets, mobile racks, broadcast carts)
• Industrial control systems requiring reliable steel chassis and filtered airflow
• Storage-focused builds using multiple 3.5" HDDs or 2.5" SSDs
• Security and surveillance systems needing lockable front access

Good to know

The chassis includes mounting rails for 19-inch racks and supports standard ATX power supplies (included unit is 400 W). Front USB 3.1 ports provide fast data transfer for peripherals or maintenance. Optional 80 mm rear fans can be added for exhaust in high-heat configurations. The lockable door and removable dust filters help protect internal components in dusty or shared environments.
