Supermicro CSE-721TQ-350B2 server chassis, Mini-ITX, 350W 80PLUS Gold, 4 x 3.5" hotswap bays

Compact Mini-ITX server chassis with hotswap storage

The Supermicro CSE-721TQ-350B2 is a Mini-ITX mini-tower chassis that includes a 350W 80PLUS Gold power supply. It provides four 3.5-inch hotswap drive bays with a SAS2/SATA3 backplane plus two fixed 2.5-inch internal bays. A single low-profile expansion slot sits at the rear alongside a 120mm fan.

Suits small NAS or edge builds.

This chassis targets builders who need dense 3.5-inch storage in a compact footprint and want front USB 3.0 connectivity. It will not suit systems that require more than one expansion slot, full-height cards, or a power supply longer than 150mm. Buyers needing additional 3.5-inch bays beyond four should look elsewhere.

Fits Mini-ITX boards and short PSUs.

The case accepts Mini-ITX motherboards and a power supply up to 150mm in length. One 120mm rear fan handles airflow while the single low-profile slot keeps the rear panel clear for I/O. Front-panel power, reset, status LEDs and two USB 3.0 ports are integrated.
