Built for High-Capacity NAS Builds

The Rosewill Helium NAS Duo is an ATX mid-tower chassis designed for storage-heavy systems. It accepts ATX, E-ATX, Micro-ATX and Mini-ITX motherboards, making it suitable for DIY NAS appliances, media servers or small-business workstations. A steel and plastic frame with a black finish gives it a clean, professional appearance in any environment.

Eight 3.5-Inch Drive Bays Define Capacity

The single specification that determines fit is the eight internal 3.5-inch bays, supplemented by two 2.5-inch positions. This density allows a single chassis to hold a large RAID array without external enclosures. Seven expansion slots provide room for HBA cards or additional networking adapters needed by storage workloads.

Mesh Front and Four 140mm PWM Fans Move Air Quietly

A full mesh front panel feeds three pre-installed 140mm PWM fans at the front and one at the rear, creating strong front-to-back airflow across the drive stack. Top mounts accept up to a 360mm radiator or additional 120mm or 140mm fans for liquid cooling. Dust filters on the intakes help keep the interior clean during continuous operation.

商品問答

Can I fit eight 3.5-inch hard drives and still add a 360 mm radiator on top?

Yes. The case supports eight 3.5-inch bays and a top-mounted radiator up to 360 mm, so both can be installed together.

Will a graphics card measuring 390 mm clear the front fans?

The specifications list a maximum GPU length of 380 mm, so a 390 mm card would exceed the supported limit.

What front-panel ports are available for external drives?

The front panel provides one USB 3.2 Type-C port, one USB 3.0 port and an audio jack.
