Deepcool Mattrex 70 Tempered Glass Case Review

Rating: 7.0.

In this review we take a look at a mid-tower case from Deepcool which features easy to remove tempered glass panels and even a tempered glass PSU shroud. It does come with a black 120mm fan but any RGB components have to be bought separately. Is this case worth the £65 asking price?

Cooling performance:

The graph below shows the results from temperature testing with all the side panels in place on the Mattrex 70 PC case.

Idle temperatures are 38C for the CPU and 42C for the GPU. This is slightly above average compared to other case reviews.

To test the maximum temperature of the components the PC is then stress tested using AIDA 64 for 10 minutes, the temperatures maxed out at 63C for the CPU and for the 79C for the GPU. These temperatures aren't too hot but I was suspicious that the restrictive front panel was reducing the cases airflow.

The graph below shows the temperature testing results with the tempered glass front panel removed from the case.

As expected removing the front panel meant that the components ran a little cooler with the GPU dropping a significant 7C and sitting at 72C while under load. These results show that although the case doesn't heat up too much during testing it has more of an emphasis on aesthetics over performance.

Acoustic Performance: 

Despite the Mattex 70 having no noise dampening material it seemed to be a pretty quiet chassis with the maximum decibel reading coming out at 42 decibels. This doesn't make it a silent case but the lack of holes and vents seem to allow it to contain more of the fan noise.

The Deepcool Mattrex 70 can be found for £64.99 HERE


  • Plenty of cooling options.
  • Easy to remove tempered glass panels.
  • Tempered glass PSU shroud.
  • Case intakes all have dust filters.


  • Only 1 plain black molex fan included.
  • No RGB lighting included.
  • Better cases available at this price point.
  • Front panel restricts airflow,

KitGuru says: The Mattrex 70 is a decent case. It's clearly focused on aesthetics over thermal performance, so you will get much better airflow with other designs on the market. For £65, however, it may be worth considering if you want a good-looking case without spending a fortune.
