1U Mini-ITX Server Chassis

The Supermicro CSE-101S is a slim 1U rackmount chassis built for Mini-ITX motherboards measuring 6.7" x 6.7". It provides a compact black enclosure for space-constrained server deployments. A single 4 cm cooling fan handles airflow through the unit.

Wall-Mount Ready Compact Server

This chassis suits builders deploying a single-board server in tight racks, wall brackets or VESA mounts where depth is limited. It is not for systems needing multiple drive bays, full-height expansion cards or redundant cooling configurations.

Single 2.5-Inch Drive Bay

The enclosure supports exactly one internal 2.5-inch hard drive designed for 9.5 mm thickness. No additional drive locations or larger form-factor bays are available inside this chassis.

Questions about this item

How do I confirm the 4 cm cooling fan is running correctly after installing the Mini-ITX board?

Power on the system and listen for the single 4 cm fan spinning; verify airflow through the ventilation slots and check motherboard BIOS hardware monitoring for fan RPM readings.

What comes in the box and what must I purchase separately for the CSE-101S?

The chassis includes the 1U case, one 4 cm cooling fan, and mounting hardware for a Mini-ITX board and one 2.5 inch drive; you must buy the motherboard, CPU, memory, storage, and power supply separately.

Which drive thickness should I choose for the single 2.5 inch bay in this 1U chassis?

Select a 2.5 inch drive no thicker than 9.5 mm to ensure it fits the internal drive bracket designed for that height.
