Awesome Tower 1/30/2020 11:26:58 AM

Pros: - Very sleek design, even though it is also a very basic design
- Cable management potential is amazing
- Glass plate very easy to remove
- RGB Fans

Cons: - No RGB controller for fans included

Overall Review: I have to say I do love this tower. It was easy to build in, and the cable management potential is phenomenal. It also has a lot of room for both bulky fan CPU heatsinks, and for liquid cooling systems. The 3 RGB front panel fans, and the 1 ventilation fan that are included and already installed is also nice.

Good but not enough 1/27/2020 9:04:30 AM

Overall Review: To be honest, this case is really cool, everything’s very good but the only problem is airflow, the font panel is so airtight. I am using the ryzen7 2700x. If I play game high graphic games, the temperature will be 65+C. Without the panel it is just 55-C.

Great Case to Price 1/21/2020 2:49:18 AM

Pros: Lightweight
Attractive
RGB
Cable Management
Space

Cons: No top fan ability
Exhaust fan not RGB

Overall Review: Overall, excellent case. I am not sure about the other reviews but the cooling is great in this thing. I am running a RTX 2070 super, and a i7 - 9700k with a Hyper 212 Air Cooler, both temps stay under 70 C while under full load with games on ultra. I have also ran the test with the front plastic panel off and saw no change in temps, so the front panel is not causing any issues with cooling with it comes to a AIR cooled machine.

The case is great for the price point. You get tons of cable management room, and fits anything you put inside of it. I actually liked how it lacks the bays for DVD or CD drives. No one uses them anymore, so why waste the space.

Only thing I was disappointed about was the exhaust fan not being RGB.

Cooler Master has been my go. 1/7/2020 11:51:47 AM

Pros: Plenty of cooling and RGB front Fans factory installed

Cons: Fan power cords are short, and I have to run them directly off my power supply. This means no motherboard monitoring, unless I buy extensions.

Overall Review: It's a great case, and I have no no issues with it at all. Power supply is easily installed and removed. The 2.5/3.5 inch drive bays are in removable trays. Cable management is great. Nearly no wires need to be shown. Which makes ligting up your system look much nicer.
