Chieftec UNC-310A-B-OP 3U Industrial Chassis, Black

The CHIEFTEC UNC-310A-B-OP is a 3U rack-mountable industrial chassis designed for server and system integration. Its construction consists of 1.2mm SECC steel, providing a rigid structure for internal components. The case is engineered for flexible power solutions, accommodating either a standard ATX power supply or an optional 1+1 redundant PSU for enhanced operational stability. Motherboard compatibility extends to standard ATX, mATX, and Mini-ITX form factors, offering a broad base for various system builds.

This chassis provides substantial storage capacity with three external 5.25-inch bays, four internal 3.5-inch bays, and an additional four bays for 2.5-inch drives. Cooling is handled by three pre-installed front fans and one 80mm rear fan to maintain airflow over critical components. System builders should note the maximum CPU cooler height is limited to 110mm. The design includes seven full-height expansion slots for installing add-in cards, and the front panel provides two USB 3.2 Gen 1 ports for peripheral connectivity.
