Rosewill Helium NAS Black ATX Mid-Tower Case — Mesh Panels & 4x 140mm PWM Fans for DIY NAS, Media or Small Business Servers

Designed for storage-centric builds, the Rosewill Helium NAS is a black ATX mid-tower that prioritizes cooling and capacity. Full mesh side panels promote unobstructed airflow to keep components cool and prevent thermal throttling. Cooling is handled by four included 140mm PWM fans that provide efficient, low-noise operation and allow dynamic speed control to match workloads. For large media libraries, virtual machines, or backups, the chassis accommodates up to 10 x 3.5" HDD and 3 x 2.5" SSD, offering extensive storage room for home or small business servers. The case supports ATX motherboards and accepts 360 AIO Radiators, giving flexibility for higher-performance cooling configurations while remaining compatible with a wide range of hardware choices.
