    Case is alright not great. Purchase 3 times
  

*by A***R on Reviewed in the United States on October 9, 2022*

I have purchased this cause a few times for pc's that I built for other people. Mostly due to the price. The side window is not glass which I prefer. Putting fans in the front can be a pain due to areas that are hard to reach but its workable from inside case with very long screwdriver. It doesn't look bad after complete build. My last case was used. I didn't order used. The accessories were missing Screws, stand offs, etc. I know whats missing because I bought the case 2 previous times, and this usually is in a small box sitting in HDD area. Taking off front panel where fans go was scratched. The case was great the first 2x but used and missing parts I don't like.

    Nice Case for great price
  

*by K***R on Reviewed in the United States on January 31, 2019*

I built a new system with this case and I like the results.I5- 9600K with  MSI Gaming Edge AC motherboard.It comes with one normal fan in the back.  I added 3 deep cool RF120 RGB fans in the front.The case steel feels sturdy.  I like the removable front mesh panel.I also like the power supply cover.  It was easy to keep most of the cables behind the motherboard.Many holes to run them out to the front where needed.The only con is I feel like my box was missing anything to help me mount the SSD in several of theadvertised positions like vertical behind the mother board.  I see holes and spots for it but you would needsome type of holder and nothing like this came with the board.I ended up mounting it in the drive bay found under the power supply holder because I had small screws for thatspot.  I may ping cooler master to see if I am missing some parts here or if I can purchase them.Overall this was the best price /value case I could find and Amazon shipping made it a easy choice.

    Helps Keep the Air Flowing Nicely
  

*by T***T on Reviewed in the United States on February 17, 2019*

Likes: The front allows a ton of air to be moved inward, while the top and back allows the air to exhausted very well.  Has three removable screens (bottom, front, and top), for easy cleaning. I like the stealthy-black color, and the placement of the power switch, audio jacks, and the two USB ports. Didn't notice any sharp metal edges inside, like found in many low-end cases. Lastly, the cover for the PSU.Dis-likes: Like others have mentioned, I wish the cover for the Power Supply Unit was removable. When using a modular PSU, it is a bit hard to plug-in more cables. Also, I don't care for the red plastic accents. More black would be better.Suggestions: It would be nice to have two more USB ports on the front, as so many things use USB, and would be handier than reaching to use the rear ports on the motherboard. Using double-sided Gorilla tape works well for mounting SSD's behind the motherboard. If you are using a modular PSU, plan out all the cables you will need to use and plug them in before installing the PSU.What's in my case:: AMD 1800X Rysen 7 CPU, ASUS ROG Strix X470-F Gaming motherboard, Noctua NH D15 SE AM4 CPU cooler for AMD Ryzen (Is a monster, a very nice monster!), Corsair HX 850, Samsung 970 Pro M.2 512GB, Samsung 860 500GB SSD, Samsung 850 500GB SSD, Samsung 840 250GB SSD, G.SKILL Flare X 16GB DDR4 at 3200, and running Windows 7 nice and cool.
