Rosewill Helium NAS Max ATX Mid Tower PC Case

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.
