## Summary description

CHIEFTEC UNC-409S-AIO-OP is a rack server chassis in black with SGCC construction, compatible with Mini-ITX, ATX, EATX and SSI (EEB/CEB) motherboards. It provides two 3.5" and two 2.5" drive bays, rear 80 mm fan support, and front support for 120/240/360 mm fans or radiators. Dimensions are 480×427×176.8 mm for compact rack deployments and AIO cooling integration.

## Long description

The Chieftec UNC-409S-AIO-OP is a black rack-mount server chassis designed for compact, professional installations. It supports a range of motherboard sizes from Mini-ITX up to EATX and SSI standards, and accepts both 2.5" and 3.5" hard drives. The chassis is constructed from SGCC steel and measures 480 mm (W) × 427 mm (D) × 176.8 mm (H), making it suitable for 1U/2U-style rack deployments where space efficiency is required.
Advantages
This rack server case offers flexible motherboard compatibility including ATX, EATX, Mini-ITX, SSI CEB and SSI EEB, allowing use with a wide range of server and workstation configurations. It supports multiple front radiator and fan sizes (120, 240, 360 mm) and a rear 80 mm fan, enabling effective cooling options for high-performance components. The chassis provides two 3.5" bays and two 2.5" bays for mixed storage setups and is finished in a durable black SGCC steel construction for reliable rack use.
Suitable for
Compact server installations in rack cabinets
Workstation builds requiring large or non-standard motherboards (EATX, SSI)
Systems needing mixed 2.5" and 3.5" storage
Setups that use front-mounted radiators (120/240/360 mm) for liquid cooling
When it may not be suitable
This chassis is a rack-oriented server case and may not be ideal for standard tower desktop use or for consumers seeking extensive external drive bays — it has no 5.25" bays and lacks a side window. Very compact or low-profile environments that cannot accommodate a 176.8 mm height or the rack form factor should consider alternative small-form-factor cases.

How to use
Install the chosen motherboard according to its form factor alignment in the rack chassis and secure it with appropriate standoffs. Mount storage drives into the provided 3.5" and 2.5" bays and connect power and data cables. Fit front radiators or fans into the supported front positions if using liquid cooling, and install an 80 mm rear fan for exhaust. Slide the chassis into a compatible rack cabinet or mount using rack rails, ensuring adequate airflow and cable management before powering the system.
What to consider before purchase
Ensure your motherboard size (Mini-ITX, ATX, EATX, SSI CEB, SSI EEB) is supported
Check available rack space and that the chassis dimensions (480 × 427 × 176.8 mm) and rack mounting type fit your cabinet
Confirm cooling needs and compatibility with front radiators (120/240/360 mm) and a rear 80 mm fan
Verify required internal drive count against the two 3.5" and two 2.5" bays
Usage recommendations
For stable operation in rack environments, use recommended rack rails, maintain clear front-to-rear airflow, and pair the chassis with compatible cooling (front radiators and rear exhaust) when populating with high-performance components.
