ASUS Republic of Gamers Strix Helios PC Case Review

Rating: 8.0.

Republic of Gamers is a very familiar name when you think of PC components. ASUS has a ROG variant of pretty everything you need when creating a custom build. The range extends from Monitors and peripherals to Motherboards, GPUs, Coolers and Power supplies. In this review we take a look at the missing piece, The ROG STRIX Helios case.

It’s been designed specially for showcase builds with AURA RGB lighting and lots of tempered glass to exhibit the components inside. However as with most ROG components you do pay a premium and with the Helios coming in at a whopping £269.99 it doesn’t come cheap. So is this case worth the cash?

The full build gallery:

Acoustics performance:

When idle, the fan noise coming from the Helios is just about audible at 38.1 decibels. The 140mm fans that come with the case are high quality & quiet which makes it a very peaceful desk companion. While under heavy load there is a slight increase in noise to 40.1 decibels but this is a lot quieter than some cases we have tested and overall these are some really good results.

Cooling Performance: 

Idle temperatures are 12C to 14C above ambient, with the CPU sitting at 35C and the GPU idling at 37C. This is pretty much as expected and is the same temperature I see regularly with my case reviews featuring the same or similar components. To test how hot the Components got inside the Helios under heavy load they were stress tested using AIDA 64 and the UNIGINE Heaven benchmark for 10 minutes.

This puts the CPU & GPU load up to 100% meaning they both produce plenty of extra heat. The temperatures maxed out at 61C for the CPU and for the 64C for the GPU. This is a good result for the Helios as the components don’t get too hot however the tempered glass will impact airflow.


  • Excellent build quality
  • Included GPU support bracket
  • RGB lighting with Aura Sync
  • Loads of tempered glass
  • Cable management cover makes keeping cables neat easier
  • Option to mount 2 GPU’s Vertically


  • Incredibly heavy
  • Carry Handles are impractical for such a heavy case
  • Only 2 slots for 3.5″ drives
  • Vertical PCIe bracket obscures other PCIe slots
  • Expensive

The ASUS ROG Strix Helios case can be found HERE for £269.99

Kitguru says: The ROG Strix Helios is a great case when it comes to build quality, aesthetics and performance. There’s loads of room for components and it’s easy to build in. If you’re looking to build a big show off ROG themed PC then you won’t be disappointed however it comes at a high price!
