Very clever cable management, strong!!!!!
A pleasure to work in, though I had to re-install fans couple times to get cable right. Extremely good air flow with 2 BeQuiet 140s on bottom and top! (I disposed the dust filters except for bottom.) Theralright Peerless Assassin works nicely. Handle works nicely to keep people from putting things on top blocking air flow. Excellent sturdy build quality, at this price. My 1st micro-atx after 30+ builds, and I'm a fan!! Mobo runs much cooler than ITX with more features and lower cost. This case is very compact!!!

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.)

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

Excellent SFF Micro ATX case!
What an amazing little case! Small yet extremely sturdy. The all metal design is perfect sleek but feels heavy in a nice way. I would almost say it's underpriced for the material quality you receive. A few recommendations for those eyeing the case. Plan plan plan and then plan again. It is truly SFF. I don't have the biggest hands and even I had issues maneuvering inside it. Things get tight real fast. Make sure to read the instal guide before you start everything MUST be done in a specific order. Also get your cable management on point. Has excellent 5 fan capcity but if you are like me and have a thicker GPU (Asus dual Radeon 7600) you'll need to pick up some ultra thin fans for the bottom of the case (15mm)

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.

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).

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!

You can’t beat the price and quality!
I absolutely love the look of this case! Jonsbo is a really good company that care about product quality and customer satisfaction. This case is priced so cheap for how good the quality is. Having a case come with a whole accessories kit is a really good touch. It goes without saying that it IS a mini Micro-ATX case so if you don’t use mini-itx parts like mobo or a sfx psu, it is going to be a VERY tight fit. There’s still plenty of room for cable routing and managment with the included velcro straps in the back panel. I was,after many many hours, able to fit a full 3fan rtx3080 in this case. Although if you want to be able to have fans on the bottom I suggest using a mini-itx motherboard as there is practically no room for error if you are using a Micro-ATX like me.
