Premium EATX mid-tower for showcase builds

The ASUS ROG Strix Helios II GX601S is a black aluminium, steel and tempered glass chassis that supports ATX, E-ATX, Micro-ATX and Mini-ITX motherboards. Four pre-installed 140mm fans and dust filters on the bottom, front and top deliver strong airflow out of the box. Dual glass panels and a diamond-grille front create a clean aesthetic for high-end hardware displays.

Suits builders who want generous radiator support

This case fits front radiators up to 420mm and top radiators up to 360mm, covering most custom-loop or AIO plans. The multifunction cover, PSU shroud and rear cable clips simplify cable routing for tidy finishes. Woven X-shaped straps make it practical to carry a completed system to LAN events. Builders who need more than two 3.5in drive bays or more than four 2.5in bays should look at a storage-focused chassis instead.

GPU clearance of 450mm decides fit for modern

The interior accepts graphics cards up to 450mm long, which covers most current triple-slot models. CPU cooler height is limited to 190mm and power supply depth to 220mm, so verify those dimensions against your chosen components before purchase.

Questions about this item

Will a 450 mm graphics card fit with a front radiator installed?

The case supports GPUs up to 450 mm, but a front radiator reduces usable depth; check the radiator thickness against the 450 mm limit before buying.

What motherboard sizes are compatible with this chassis?

ATX, E-ATX, Micro ATX and Mini ITX boards all mount in the Helios II.

How many drive bays are available for storage expansion?

Two internal 3.5-inch bays and four internal 2.5-inch bays provide space for multiple drives.
