I ordered this case the day it got released, before seeing anyone review it, or without thinking twice and all I have to say is...This case is fantastic. I decided to downsize from a Cooler Master Masterbox Pro 5 RGB (as seen in the pictures) and this case is perfect. My temperatures for my GPU (Vega 56) and my CPU (Ryzen 7 1700x OC'd @4.1ghz) are running cooler than ever. My GPU rarely gets about 55c, even during extended gaming sessions. In my old case, it would hit 80c all the time. My CPU runs a bit cooler now too, and my VRMs are nice and chilly barely reaching 60c. That's a far cry from the 95c temps on the VRMs I was getting in my old case. I have ZERO issues that others seem to complain about. People are calling it the "masteroven". Not even close. What's so hard about adding fans?? The Deep Cool fans I have (3 120mm RGB and 2- 140mm RGB) allow it to run very cool. Air flow is not an issue at all. I have the very bottom 2 fans and the bottom front on pull with the fan on the 120mm rad and the 2- 140mm fans on top exhausting, taking advantage of the nature of heat rising and also getting excellent airflow through my blower style GPU and also across the VRMs of the motherboard. The PSUs fan exhausts up as well, following the path of the airflow.Building inside this thing was a dream, having built 8 PCs in the past year and a half, I have to say its one of my favorite cases to build in. Plenty of room to fit full size components, and plenty of room on the back of the motherboard tray for cable management with plenty of hold-down points for zip-tying.It looks awesome and exceeded my expectations. My next step is definitely a custom loop water cooling setup for both the GPU and CPU. I'll update this review when that happens.

Update... I ordered a new one, and they changed how the power supply goes to a more conventional system now.This is my first pair of PC builds since before several of you were born. The case is open yet compact. It's attractive too. I enjoy the simple utilitarian approach. The one quirk is having the power supply on the top front. This means they have a jumper power cable that runs to the rear so no I/O switch for the PS other than if you pull the cover and reach up to it. Cable management is pretty simple though and it leaves the rest of the case open. It does make the case a bit more top heavy than others, but it's shorter so that might not be a huge concern. This computer build is more utility/streaming and I'm glad I upgraded to a bigger case for my gaming unit I'm building. But I would certainly buy this one again for a basic non flashy build.

This PC case is exactly what I was looking for. At this price point, it's the most compact tower that can accommodate an ATX mobo. It's sturdy, semi-modular, lightweight, and the patterned dust filters look great. There's plenty of room for cable management and I've had no issues fitting everything inside.The case can be inverted if you pop out the feet from the bottom, which is one of the best things about it. You won't have to worry about missing out on the view panel if your PC needs to sit on the left side of your desk. I don't know if there's a better budget-friendly option with this functionality.The downside of this case is that it has the nickname "MasterOven" for a reason. The holes along the chassis are too small and spaced out to allow for optimal airflow. I've had a significant increase in temps and the case is warm to touch when my PC's under stress. If you have the right tools, you can cut out holes for your fans, but the design could've been better in the first place.The front panel is a little flimsy when plugging in a USB cable and it also would've been nice to have the option of glass. My acrylic panel arrived with micro-scratches and I still need to buff them out.The last two bits mentioned aren't deal-breakers, and if it weren't for the airflow problems I'd give this case 5 stars. I'd recommend getting it if you need something compact and can make the modifications for better airflow.

I got this case to replace a massive full tower case because I wanted to reduce the footprint where I keep it under my desk. This case is 1/2 the height and 20 pounds less than what I had (empty). It will fit a full size ATX MB. The power supply mounting is a little tricky, because the entire unit is fully enclosed inside the case (including the PS power switch). This comes with an extension plug to reach the plug from the inside of the case (now mounted in front) to reach into the back of the case for the external power cord. The only issue with this is the switch for the Power Supply is now inaccessible, whereas if I want to completely shut off power, I have to unplug it. CD ROMS are a thing of the past and there is no mounting options in the front of the case (doesn't bother me because I don't think I used a CD in over 3 years). There is 4 mounting pads for SSD, or 3 mounting pads for mechanical hard drives. Otherwise, the side panel is clear plastic but still looks good and is lighter than glass. The USB's and power button are on the side of the case, so if you have a desk with an PC enclosure, this could be a problem. The sound is average as I can still hear the fans when this is turned on, but it is quieter than my other case that had an overkill of 6 fans. Overall, I don't hate this case, but it fills my needs.
