Sleek and Tight Case, but plan out your build what to put in there.
This is a well built and sturdy case, its cable management is near perfect for what it is. USBs are a little lacking so make sure you have a good amount on back of Motherboard, but there is what you see in the picture. The Power button is unique and neat but it almost like a unfocused laser. Pay attention to all of the parts in the case as it has some nice extras that most wouldnt notice like GPU Riser. I would highly suggest a modular small form power supply for the extra space and fitment but the full size will work. Overall im very happy with the quality, the value, the airflow and the functionality and it's a very nice looking case. good job Jonsbo

Great value, Sturdy Sleek and Stylish!
I just wanted to give a shout-out to this brand and their product before I build (orange version). Though I had never heard of them before, they seem to know what they doing and have an intuitive grasp for how to effectively blend Form and Function. I've uploaded some photos from the unboxing, one which includes a view behind the removed side-panel and an example of their cable management accommodations (though there are more within the case body). This 'use-case' is for a small video production studio and I needed it to fit on a short-scale skinny table that I'm using as the desk, which would also snugly house my micro-ATX motherboard. Needed room for the camera and the lights, afterall! Honestly, it's a lot nicer than I was even expecting - particularly for this price. If you were on the fence about grabbing one before they run out, I'd highly recommend it! (Will upload more photos and commentary once the build is complete) ==== UPDATE: Well, my view on the manufacturers and designers of this product have not changed, but have actually improved somewhat - or let's say, I was pleasantly surprised. I have seen some reviews stating that the instructions are not clear. I emphatically disagree. They ARE minimalist, but you can tell a lot of thought went into the point of view of the person reading the instructions, and how they were laid out, such that an average builder could mostly understand and not have to guess. They label ALL of the screws and components with their own alphabetic letters (pictured), separate each piece-group into a bag with the letter actually printed on it and, they provide spare parts of which I actually did need one - and even give you multiple arrangements for how to hang your power supply. I was able to follow the instructions from beginning to end and I actually haven't done an in-case build for a long time. My last build was a TEST BENCH and you can see some photos for that if you look at my other reviews. SOME THINGS TO CONSIDER: The quarters ARE tight in the case of a Micro-ATX, particularly at the bottom of the case (pictured), in that there isn't much clearance between the mobo and the case itself. This was only an issue when I attempted to connect the front panel wires included in the case. Speaking of which, you want to make sure your motherboard has the USB-C front-panel pins on it (wire is pictured), because mind didn't, and now the wire is just kind of hanging-out! (not their fault) But even these wires are labelled as well and the directions are very clear on which is which, as they're all differently-sized as well. That being said, you may want to connect such components as may be required to interact with any of the pins on the bottom edge of your mobo BEFORE you screw it into the case, it just might be a little bit more difficult to get to afterward. But not impossible. I stand by my assessment that for this price range, and even significantly above it, this is a very well-designed and sleek product, as well as being thoughtfully put together and presented to the customer. I will upload some additional photos of the bags and the instructions for now, and when my lighted fan finally comes in, the finished build. For now, I'm just raw-dogging it with the Heatsink block, but no fans (except the PSU)! And yes - it still works. My temps stayed in the 40-50 range at most, and often far below. Pretty amazing, actually. (note on PSU: I am NOT using a modular power supply unit on this build, repeat am NOT, and yet I still had room for all the cables in that little management cubby on the back which is pictured. So even if you have a power supply for which you cannot remove/obviate unnecessary cables from the brick, they still managed to all fit here. And I will add that to my pictures when the fans arrive as well. Thought that might be something worth mentioning.)

5 stars!
I haven't built a computer in decades... Back in the day when you'd cut your hands on unfinished edges. This is by far the nicest case I've had. It has supreme cable management and accessibility all around for a clean look that's perfect for matx mobos and full sized graphics cards. I love the atx PSU front mounting option. Came together quickly, stays cool... well designed, machined, and documented. Thanks!

A Small Case with Big Possibilities!
This was my very first PC build and from someone with no previous experience in this hobby. The quality for this is great. From the coating, panel thickness, cut quality, and components used, everything is pretty much perfect. Here is the parts lineup that I used for the build: ASUS 3060 (dual fan), Thermaltake smart 600w PSU (Non-modular), ASRock B550M-C, ryzen 9 5950x, WD Blue 1Tb HDD, 3 Be quiet 120mm lux wings (can't remember if that's the exact name) intake fans (two bottom mounted, and reversed the rear to be an intake rather than exhaust), 32gb Corsair vengence ram, and an Arctic Liquid Freezer III 240mm AIO (stock without modification to tubes) with 2 120mm PW12 Pros I believe. These are the main space consuming components. With that, I was able to put everything together easily in this case given it's well designed layout with ample space for cable management in around 4 hours (still new to this) but there was no problems that were of the case's fault. I loved this build and how it all came together. This is a very forgiving case in my opinion and would be good for people new and experienced to build in and are looking for high quality and functionality. Not to mention, cooling temps for my CPU are rarely above 73c under a gaming load with very very brief spikes of 76c (not something I would believe is even remotely related to the cases design). For the GPU, temperatures peak at 71c and are often below that even under load. Ambient case temperature for my situation is 27c while idle and maybe 34c while under load. So airflow is also a non-issue with this case design (something I was worried about). Fans stay quiet even under load (rarely do they exceed the 65%-75% power window) but that's subjective I suppose. So I consider this a 10/10 amazing case. (The handle also is a nice solid touch for if I want to use this for gaming on my TV it's easy to move). For reference, the temperatures were obtained under load running the following games with the settings nearly maxed out: Monster Hunter Wilds and World, Helldivers 2, 7Days to Die, and Space Marines if it's of any value or consideration. Buy it! Won't regret it! (Plus you get some extras in a nice package which also have good build quality and are very functional if you need them).

Its okay. Neat, but has some caveats.
This is a renovation build for a client. We took an ASrock B450m Steel Legend matx board, and its AIO from a full sized case, and downsized into this guy. First of all, this is not a good case for anyone doing a first build, or even a newbie. You need to know your hardware well, and you need to know exactly what is necessary and what isnt. There is no room for error, no room for extra wires, you need to carefully calculate exactly what you need as there is room for only what you need in the back - as with most sfx builds. But, it is a very nice case, all complications aside. Glass side panel, good solid construction, innovative, definitely fun to build in if you like a challenge. Second, and why there is one star missing - it is over-engineered in some parts, and under-engineered in others. Both apply to the psu mount. There is a two-fold system for mounting the psu. A tension bracket in the back, and a hard mounted bracket in the front (glass side). Front side makes sense, no issues there, little bit unnecessary but adds to the rigidity of the case, so that is nice. Back side, stop. The (seemingly) thumb screws are A. Too short to be thumbscrews and B. Flat head, thin, keyed. Pick a screw style, stick with it. Absolutely no excuse to have a custom flathead screw with no phillips adaptation. Silly. Next, also factored into the deduction, the specs say a 240mm aio fits up top. Nowhere is it mentioned that it is 100% dependent on the psu you choose, and aio manufacturers’ fan mounting hardware. We are talking less than 1-2mm clearance, and I was really pushing it. Again, sfx build probs, but the listed specs say nothing about it - be a bit more transparent. Final complaint are the dust screens - they are internal. Why. Looks cool, but not exactly practical. Other than those complaints, great case. Really, minor issues. Went together well, feels solid. Handle on top, bit over engineered with the tension system, but cool and very solid feeling. It is set up well, they clearly did a lot of homework! Just overthought somethings, forgot about others. If you do buy this, just know it requires quite a bit of work to remove the modules for the psu and aio/fan rack, but worth it, imo. I would highly suggest getting the Silverstone Vida aio, and you will have more room for activities. The one pictured is the asrock phantom one from a few years ago. The rear exhaust is a 120x15mm Arctic slim fan. Psu is an MSI MAG compact 750w - I do not recommend it - get the SFX psu from someone else - this one is small enough, but its just a slim version of a full sized psu, not an SFX psu. GPU is an older rx 590.

Amazing, But not perfect
I will say, this case is amazing and I highly recommend it, but I just want to oint out specific things to look out for when working on it cause, I got a few headaches. One, This case supports 2 120mm at the bottom, but I have no idea how, cause no matter where I try to put it, only like 2 holes actually fit, and thats good enough for a fan but doesnt feel good enough for the price tag to me two, the slider to pull out the top to put in 2 120mm fans at the top can sometimes get cought on a cable going through the pass through on the top of the case and get stuck or cut a cable, so rememeber when putting it back, to pull down some of cables slightly so they dont get clipped and the slider can go in properally three, If you think the case is gonna be as colorful as the picture shows, not really. its like the X box series X in which only in certain angles you can REALLY see the color, but all you will really see is the black 90% of the time. Lastly, The Dust Fuilters have such a weak magnet that even just a slight nudge can make them fall right off, they are good enough to pull and leave, but even some of the screws if slightly crooked can screw up the fan filter, or even if you dont pull screw in the fans, which is just annoying sometimes Its an amazing case to work in, really simple and easy, but these tiny tiny things I wish I knew from the start so that I didnt even up spending 5 hours instead of the typical 3 hours just looking through manuals

This is a great, well designed and carefully thought out case
Case is being used for AMD Ryzen 7700 with Radeon RX 9070 (full build below) If you're looking for a great mini tower case this one is well worth the money. It's well put together, no sharp edges and lots of thought put into the design. Make no mistake, it's a tight fit and you should learn from my mistake of putting the fans in last! That was a pain - instead, get the motherboard fitted along with the CPU but wait on putting in the heatsink - take the time to add in your fans and route their cables carefully thinking about which goes where and how they'll be controlled (the power attachment is marked). The top fans (I avoided water cooling this time round) attach to a convenient slide out tray controlled by CPU-OPT, the bottom fans are screwed directly into the case controlled by SYS-1 (Gigabyte MB). Bottom fans are intake, upper fans are exhaust. Take your time, when the power cables are being routed it gets real tight real fast! I ended up carrying over a 2.5" SATA SSD and the case has a special bracket to neatly mount it behind the PSU - brilliant piece of design! The instructions are clear and easy to follow, I recommend taking time for a quick read through before assembling. Dust covers are magnetic and time will tell if they are sufficient. I doubt I'll be taking this anywhere but the built in handle makes it easy to move around. I've already clocked a few hours of Elite Dangerous and the CPU/GPU have not broken 40C with the fans all tuned to be 'silent'.

Perfect Case
I had a full ATX PSU left over and wanted to use it in a small build. Now, rightfully, most SFX PC cases don't support full ATX size PSUs... why would they? But luckily, this one supports both SFX and full ATX size PSUs, yet is still quite small. Very very easy to build, looks great. Comes with a sturdy handle to install. All around, highly recommend.
