NAS-Ready Storage Chassis

The Rosewill Helium NAS Max is an ATX mid-tower case built for storage-heavy workloads. It supports up to 11 internal 3.5-inch drives and two 2.5-inch drives, making it suitable for DIY NAS appliances, media servers or small-business file storage. The chassis accepts ATX, E-ATX, Micro-ATX and Mini-ITX motherboards, including BTF-compatible designs. A black steel, plastic and tempered-glass exterior fits home, office or rack-adjacent environments.

Build Flexibility && Clearances

Seven expansion slots give room for add-in cards such as HBA controllers or 10-gigabit networking. The front panel provides one USB 3.2 Type-C port, one USB 3.0 port and audio jacks for quick peripheral access. Graphics cards up to 410 millimetres long are accommodated, while CPU coolers up to 185 millimetres tall fit under the side panel. Power supplies up to 200 millimetres in length are supported. Dust filters are included to protect intake areas.

Airflow, Thermals && Acoustics

A mesh front panel feeds three pre-installed 140-millimetre PWM fans, with a fourth 140-millimetre PWM fan mounted at the rear for exhaust. Additional mounting points allow three 120-millimetre or two 140-millimetre fans on top, plus alternative front and rear sizes. Radiator support reaches 360 millimetres on top and 120 millimetres at the rear for liquid-cooling options. The four included PWM fans balance airflow and noise under typical NAS loads.

Questions about this item

How many 3.5-inch drives can the Helium NAS Max hold before I run out of bays?

The case provides 11 internal 3.5-inch drive bays, so that is the hard limit for mechanical drives.

What are the pre-installed fan sizes and noise behaviour when the system runs continuously?

Four 140 mm PWM fans come fitted — three in front, one at the rear — and will spin up or down based on temperature.

Which motherboard power connector style must I already have for the BTF-ready layout to work?

A BTF-compatible motherboard with its main power and front-panel headers on the rear side is required.
