Review: Matx case done right - This one pretty much checked all the boxes for me. I really wanted a clean looking case slightly bigger than typical SFF cases that also had glass side and good airflow without mesh (or optional mesh). This is the redone model that really deserves better reviews. You can pretty much ignore a lot of the problems mentioned in old reviews. Has USB-C, there's plenty of AIO space (mine is mounted with tubes down and will only match 2 thread holes..otherwise tubes up is the normal mount position), will fit a sapphire 7900xtx without an issue without the need of a sag bracket, easily fit 2 SSD's, and a 140mm PSU. I opted to run corsair PSU with their SFF cable kit. Makes the cable runs really short. Temps during gaming with a 5600x/7900xtx are 59-62CPU/60-65GPU. These are on 1800rpm fans as well including the AIO, so the system runs very quiet. Overall I love this case, and would highly recommend to anyone going for something different. Side note: It was a huge pain finding the dimension chart, but I've attached one that should really help with the overall layout. Someone had posted it on another site where they sell, but I could not find this info from the manufacturer direct.
Review: Solid and challenging case, not for new builders. - Zero cable management. None, absolutely no cable management. I had to run cables under the mobo. This case is not for every one. If you're new to PC building, don't buy this case unless you're ready to challenge yourself. I was able to squeeze in an MSI 4080S Suprim X. A 336mm card at 4 full slot thickness. If you don't figure out a decent way to get your large card in, you won't be able to complete the build. I ended up scratching my card trying to force it in. But it 100% fits with about 5-7mm of room left. Get a 130mm PSU. I have a 140mm psu and I feel like it's too close to my card. You will have to get rid of the ssd mount for more room in the case. Unless you wanna use a 2.5" drive. You will need an l or u shaped pcie adapter. The side panel has very limited room. I'm currently using a U shaped adapter and the cover is still too big that I can't place the panel on. But I was able to add mobo standoff screws and use that to give me space. So if you don't wanna go through bending your power cables, get a flat/flushed pcie adapter. The company this case came from, I had a pleasant experience with. The side panel came broken. I picked up the box and I could hear the glass trickling off the case as I turned it. I went through desertcart to send them a message about the panel. They sent a replacement within about a week or so. Pretty quick for being over seas. While my experience with them was brief it was good, so I would say their customer service is good. Specially since they sent me a new panel by simply saying it's broken. All in all, it's a great super solid case with no cable management (good thing if you like a challenge like me) air flow is good too. You will just need a strong fan, i have a 127cfm fan I use as an exhaust and passive intake.

## Questions & Answers

**Q: A lot of reviews about stripped screws. Has this issue been rectified?**
A: I haven’t noticed any problems. If I remember some of the screws needed a lot of force to screw in. But this case is a cable management nightmare. Be ready to build and in build it multiple times just to re route one cable under the motherboard to look better

**Q: Can you use a vertical mount and riser cable with this case if you want to?**
A: No, it only has four PCIE slots/brackets

I wouldn’t mount the GPU vertically regardless as with the existing configuration you are maximizing cooling efficiency. 

Even with 3080/90, the GPU fans usually are kept in the lower RPM since the case fans already push air straight into the GPU.

**Q: This is support 140mm fans and a 280mm radiator?  Or is it 120/240?**
A: 120/240. There is 280/320 room on the right side of the case but that is where the GPU goes and it will cause interference. For the CPU you are limited to 2x120mm fans on the left side and a 120mm fan at the top right (attaches to the top of the case).

**Q: Can we please get an ATX version of this case?**
A: Sorry my friend, it is a MATX Version, can not support ATX motherboard

### ⭐⭐⭐⭐ Insanely good case
*by E***D on December 23, 2024*

This thing is actually a cheat code for those looking to downsize their PC without taking up space or too much money. Usually, for a build this size, you'd expect to have to use an ITX motherboard, but this just takes an MATX board and flips it around. Genius design! Saves space, good temps, and amazingly doesn't require a lot of complicated installation. It's just like any normal case, just without the back panel for cable management. I just wish there were a bit more space for cable management, but given the size, I won't complain too much.
