Premium White EATX Mid-Tower

The ASUS ROG Strix Helios II GX601S in white is an EATX mid-tower chassis built for showcase builds. An aluminium front panel with a diamond-grille pattern and 3D-structured filter fronts dual tempered glass side panels. The frame uses steel, ABS plastic and aluminium to support ATX, E-ATX, Micro-ATX and Mini-ITX motherboards. Four pre-installed 140 mm fans ship in the box for immediate airflow.

Pre-Installed Fans and Cable System

Four 140 x 28 mm performance fans come fitted at the front and rear, removing the need to buy separate cooling for a standard build. A multifunction cover integrates graphics card holders, a PSU shroud, a cable cover and rear cable clips to keep routing tidy. The I/O panel adds two USB 20 Gbps Type-C ports, four USB-A 3.0 ports, an ARGB lighting button and a fan-speed PWM switch for direct control.

For Large-Card Builders Needing Portability

This case suits builders who want a clean white aesthetic, room for graphics cards up to 450 mm long and CPU coolers up to 190 mm tall, plus the ability to carry the rig to LAN events using the woven X-shaped straps. Radiator support reaches 420 mm at the front and 360 mm at the top for custom loops. Buyers who need more than two 3.5-inch drive bays or a PSU longer than 220 mm should look at a larger enclosure.

Questions about this item

How often should the bottom, front and top dust filters be cleaned on the Helios II?

Remove and rinse the bottom, front and top filters every few months; the 3D-structured front grille and aluminium diamond grille make them easy to detach without tools.

Which thermal limit is reached first when the four pre-installed 140 mm fans run at full PWM speed all day?

The 190 mm CPU cooler height clearance and 450 mm GPU length limit the size of components that can exhaust heat, so oversized coolers or cards become the bottleneck before airflow does.

What is the typical noise and heat profile when the case runs continuously with the pre-installed fans at maximum RPM?

Four 140 x 28 mm performance fans move high volume at moderate RPM, keeping internal temperatures low while noise stays at a level suitable for a quiet room.
