Product details

The ASUS ROG Strix Helios II Black is a premium mid-tower computer case designed for gaming enthusiasts and PC builders seeking exceptional thermal performance and versatile component compatibility. This successor model features a robust steel frame construction with tempered glass side panels on both sides, providing full visibility of internal components while maintaining structural integrity. The case supports E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards, accommodating extensive hardware configurations. With dimensions of 51.5 cm in height, 25.5 cm in width, and 56.5 cm in depth, it offers substantial interior space for high-performance components.

Thermal management is prioritized through multiple fan mounting points, including support for up to three 140 mm or 120 mm fans at the front, three 120 mm fans at the top, and one 120 mm fan at the rear, with radiator compatibility for liquid cooling systems up to 420 mm. The front panel includes two USB 3.2 Gen 1 Type-A ports and one USB 3.2 Gen 2 Type-C port for high-speed connectivity, along with standard audio jacks.

Storage options are comprehensive, with support for up to four 2.5-inch drives and two 3.5-inch drives, plus additional mounting possibilities. Cable management is facilitated by dedicated routing channels and velcro straps behind the motherboard tray, ensuring clean builds and optimal airflow. The tool-free design simplifies installation with removable dust filters on the top, front, and bottom, and a hinged side panel for easy access.

The black finish provides a sleek aesthetic that complements ROG-themed builds, while the integrated RGB lighting control allows synchronization with compatible ASUS Aura Sync components. This case is engineered for users who require reliable cooling, extensive hardware support, and a professional appearance for their gaming or workstation setups.
