Good Build Quality
It has fans that already come set up and has a lot of space to work in. Very good quality and nothing felt cheap on it. I also like the mesh they put on the outside, gives it a very clean look. It’s a very good buy.

Best value case
Did this one up for a customer, and I gotta say, we couldn't be happier with it, very good value, spacious, easy to build in. The included fan hub is nice and the included 3 140mm rgb fans move air like nobody's business

Excellent case, great quality, great black aesthetic, great wire management.
Threw together an air-cooled black gaming rig with this. The case was flawless, everything lined up and I surprisingly had ample space to drop in a Peerless Assassin, which is not little by any stretch of the imagination. I may just buy another even though I do not need it. :)

Best value case
Had a nzxt h510 before this. Needed more airflow and cooling for my 7900xt and it definitely helped. Got an extra p14 for front intake, 360mm aio for cpu at the top and I couldn’t be happier. Basically no visible wires except gpu perfect for cable management, roomy to work in nothing was a tight space while connecting the cables

Far better than my old case.
Only downside for me is that it gets incrediblely without any good reasons. I had to manually set the fans to running at 40% and experienced similar great temps as it provided when it ran like a jet engine.

Great case for the money!
For $65 this case is hard to beat. Has all the room you'll need for high end GPUs and CPU coolers. It was easy to build in but I'd say the case itself is a tad flimsy.

Great case for the price
Bought just to throw some spare PC parts together. Didn't want to drop $100+ on a case from microcenter. Very happy with the case, fans seem decent. Would buy again anything from them.

Easy build
I bought this case for a desktop computer in my electronics lab. It was a nice easy build, running with the included and. A Peerless Assasin cooler, and RTX graphics. I can't even hear it running under the desk. I would recommend the product.

Espacioso y bien contruido
Es un excelente gabinete aunque si es espacioso, lo cual es bueno si quieres suficiente espacio para ventiladores y una tarjeta gráfica grande. En mi caso el espacio me ayudó a poder montar todo sin problemas, sin batallar. Buen flujo de viento.
