Good Case
Good case for the price. Lots of room for cables in the back. PSU is inside the case but there is a hole to pull the cables to the back for a cleaner look. Good airflow and overall solid case for the price! Got it on sale for $40! Can't beat that!

Perfect mATX case
Used this case as my first PC build. I wanted a small case to fit in a shelf by my desk. The dimensions were perfect without choking the air.It’s mainly cooled by 2x140mm Artic P14d and 3x120mm Artic P12s. Very good airflow, I used ChatGPT to help me optimize the fan curves for the most optimal cooling configuration. I was able to fit 3D printed air ducts to assist in cooling.Case looks great and no issues with cables.

Great overall case! Questionable airflow choices
Overall? An excellent budget-friendly case that has everything you need with a very clean-looking design and compact size. I do have some nitpicky things regarding airflow but for budget-midrange builds this is perfect for a case under $60.Pros: Clean aesthetic with 2 magnetic dust filters. Easy to build in and the lack of psu shroud allows for more air to circulate. Front IO is more than enough for budget in mind. Can support a 240mm aio in front if desired. Clean cutouts for cable management despite compact design.Cons: Airflow is questionable. The dust filters have a hole printout design that makes the case look as if it has larger holes for airflow, but the actual holes behind the filter are significantly smaller. This caused temperatures to get higher than expected. For reference, I used an RX 6600 and an R5 5600 with a stock cooler. With 2 140mm fans in the front and 120 in the back for exhaust as well as a stock CPU cooler, my temps were reaching 80 degrees under load. After getting a cheap aftermarket cooler and adding 2 extra fans on top and bottom for intake, temps for GPU and CPU dropped to around 70 under load. After some tinkering with fan curves, I got an optimal fan noise to temperature ratio. If the holes on the actual case were the size of the dust filters, then I would have not needed to buy 2 extra fans and a tower cooler, luckily I had some budget to spare. Coolermaster, if you do a refresh of this case, please address airflow issues on the front intake panel. Doing so would make this, in my eyes the BEST budget case in the market.All in all, I highly recommend this case, especially if you're on a budget. Just don't expect a 4090 and a 14th gen i9 to breathe here.

Very worth the Price
For 38$ you cant do better. It's 38$ so yes don't expect 100$ worth of stuff. It's EXACTLY perfect budget case. So yes you get one fan but you get a solid case. Clean glass and its light. The magnetic dust covers slip off super easily when handling the case so if your gonna move it alot I suggest a little hot glue to help that stay more on. Or just be careful when you move it. I tend to move my pc around alot from house to house. This is a solid buy with plenty of space.

Perfect for a budget build for my mom
This is my 2nd full build in 2 years using pcpartpicker. This one a budget build for my 80 y/o mom to get her up to Win11. The feet on the side are weird, as I can't imagine you'd want to rest this on its side with a monitor on the glass. I could remove the feet for a tigher fit, but I suspect that might create more problems.I have no concerns about Airflow as I only installed a low end processor that I don't expect will get too terribly hot.I saw one reviewer struggle to get the power supply screwed in, but you have to remove a bracket to mount to the power supply first. It might have been easier if the bracket wasn't attached first.Overall, quality seemed fine. Cable management was a breeze. All mounting screws were included. Honestly I would have been fine with a metal (or acryllic) side panel over glass to save a couple of more dollars since this is a cheap case, but that's just me.

Cheap case, worth the money
This is a cheap case. It's not that easy to build in, at least for people at my expertise level (= not total beginners but not experts either).There are a couple of spots that end up hard to reach, a few areas with very tight clearances. In general I don't think the space inside the case has been used that well -- it ends up being fairly large but with only 1 3.5'' mounting point, and only 2 2.5''. You can get those in a mini-itx case, pretty much. I also had issues I normally don't have connecting the 2 front USB-A ports to the motherboard (but the motherboard was a contributing factor). Accessing some of the motherboard standoffs/screws is quite hard, and the case would benefit from the ability to remove the front panel.The main positive point is that I was able to fit a fairly tall cooler (Thermalright Assassin Spirit 120 EVO) without any clearance issues. It would not have been easy in a narrower case.Thermal-wise I can't complain, my CPU is in the low 60s and my GPU is doing about as well as it ever did. However my build is fairly low power, maybe using 450W at peak, so there's not a whole lot that the case can do to create issues there.I especially disliked that it comes with almost no written instructions -- there are some diagrams of what to do, but no explanations in plain English. This is fine if you just need a reminder but if you don't know what you're doing then you won't get any help from the included material.In general it's not a bad case, especially at the price, but it does look and feel fairly cheap, and the design and ergonomics are certainly not what you'd find in a more expensive product. I would recommend it to someone who knows what they're doing; if you're a total beginner it can still work, it's not impossible to manage, but I'd go for something designed a bit more carefully.

Great Budget case.
The people complaining about airflow must not know how to set pressure properly. I get amazing thermals with my old trusty Noctua all air setup. The only bad thing are the popout expansion plates. But every budget case has them, so it was expected. For the price this is one of the nicest mini-itx boxes you can get imo.

High Quality Build in small form
Fantastic Little case. Ryzen 5 5800xt, RTX1660 super, Hyper212 CPU cooler, 600W PSU. Silent and sleek.
