ASUS ROG Strix Helios II GX601S PC case EATX, 450 mm GPU support, 4 × 140 mm fans

The graphics card can be up to 450 mm long and an air cooler up to 190 mm tall, so the case does not hold back today's flagship cards or large tower coolers. Behind the front panel there is room for a radiator up to 420 mm, and up to 360 mm under the roof. According to ASUS you can fit a 360 mm AIO for the CPU and a second 360 mm radiator from a liquid-cooled graphics card at the same time, with space reserved for the pump and reservoir of a custom loop as well.

The case ships with four 140 × 28 mm fans: three in the front panel and one at the rear. The manufacturer quotes a noise level of 29 dB(A). Up to three more 120 or 140 mm fans can be added at the top. A PWM button on the front panel switches the fans between light and heavy airflow without a trip into the BIOS.

Pressing a button at the rear releases one side panel; the glass is hinged at the bottom, so it can rest at an angle or be lifted off entirely. Two removable brackets let you fit fans and radiators before putting the whole assembly into the case. The graphics card is secured in its slot by a tool-free clamp, and the rear PSU bracket detaches so the power supply slides straight in. No power supply is included; it can be up to 220 mm long.

A multifunction cover hides cabling and supports the graphics card at the same time, and its position can be adjusted for an ATX or EATX board. There is also a PSU shroud, a cable cover, rear cable clips and a grommet channel with velcro for two cable bundles. Six drives fit in total: four 2.5″ and two 3.5″ positions. With eight expansion slots, a thick graphics card still leaves room for other cards.

The front panel has four USB-A ports (USB 3.2 Gen 1) and USB-C ports running at 20 Gbit/s that support fast charging of compatible devices at up to 60 W. Alongside are audio in and out, power and reset buttons, an ARGB lighting button and a PWM fan button.

Both side panels are 4 mm tempered glass set in a brushed aluminium frame. The CNC-milled, anodised aluminium front panel has a diamond grille pattern with a 3D-structured dust filter behind it, and there are filters at the top and bottom too. The integrated ARGB controller supports Aura Sync. The case weighs 18 kg, and X-shaped fabric carry straps, tested by the manufacturer to 50 kg, make it easier to move.

Gamers building around a flagship graphics card and a 360 mm AIO who want everything to fit without compromise; water-cooling enthusiasts planning two radiators or a custom loop; and anyone who wants a glass-sided showcase PC that is easy to build, easy to keep clean and can still be carried to the occasional LAN party.
