Good case for ventilation of second one we have purchased and use. Good customer service. Helped right away.

Great value, but don't push its limits

Reviewed by: Hasan
- Great value for money. - mAtx form factor is great - Good i/o - Minimalist Design will make it fit into any gaming or productivity setup
- Thermals are not good (components will get hot under load). - Only has 1 case fan included, which doesn't help its thermal issues
This is a great mAtx budget option that I would recommend to anyone. However, you should definitely get more case fans to address its thermal issue. I added a total of 4 fans (2 in, 2 out), which improved the performance a lot, but came at a cost. Only use it with budge/mid-range setups or you will run into overheating issues.

Good, but not perfect

Reviewed by: Haseeb
Really good looking case with amazing airflow. Magnetic dust filters are really good. Overall, I'm satisfied.
Although this is a con with every acrylic side panel, it stains and scratches easily so I recommend paying a little more for the tempered glass model. The biggest con is that the front USB ports often randomly stop working. I would send it in for warranty, but do not want to rebuild my rig.
Good case for the money, however, be aware that the front panel USB ports are somewhat problematic. Also, pay a little more for the tempered glass model, trust me it's worth it.
