I love the size of this case, it’s clear that it’s not a higher end case, but it’s still fairly easy to build in and looks great when it’s done.

I used this with the ASUS Prime b450M-A/CSM motherboard which didn’t really fit well (probably my mistake) but it’s overall very good, the airflow is great and I love the glass xD Works pretty good with my PC, although if you have more money I’d recommend going for a bigger case that has more fans.

Great quality

This case looks great and vents well. I like it’s size, internal space and I/O layout. Especially for the price. Very happy with the final build.

This is a nice little case. It’s very modular, can be reconfigured to position many different ways, and leaves a reasonable amount of room for cable management. I’d say the only drawback is that it can be difficult to discern where things go, eg the front fan slots

Great case and at a great price. Just built a new computer and I didn’t need or want anything fancy. Just a regular case that would get the job done. That’s what this case accomplished!

The case is fully vented on three sides–bottom, front, & top. It includes two magnet faces to provide the pattern seen, but they are not required to be used (allowing even more ventilation). As far as ventilation is concerned, my biggest issue is that the only 3.5 bay is on the back side of the motherboard–between the motherboard and case cover. That seems tight to me. Overall, the case is not quite as sturdy as I expected, but it is acceptable. The power / usb / front sound panel is relocatable, but a little flimsy, but o.k. I have purchased a second one after setting up the first one.

It’s a case. Plenty of cabling options.
