JONSBO/JONSPLUS Z20 Black Micro-ATX Mini Tower PC Case,with Detachable Carrying Handle, Mini Size

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.)

What an amazing little case! Small yet extremely sturdy. The all metal design is perfectly sleek and 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 2.5 or 3 slot (Asus dual Radeon 7600) you'll need to pick up some ultra thin fans for the bottom of the case (15mm)

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

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!!!

It's a great sleek metal frame compact case for a MATX build. Packaging was excellent and well protected. Got this on sale, so price was great. This was the first time I built in case this small, so it was a learning experience. The side panels came off easily. Some of the screws inside the case were screwed in too tight, so I ended up stripping some of the screw heads. Getting the motherboard in was a little difficult getting the screw holes to match up. I think I spent an hour trying to get all the screws in, but the case had one less motherboard screw hole to what my board had. This case has some sharp edges inside so that's something to watch out for, because I did cut my finger. This is a great compact affordable case. Build quality is solid. Easy cable access and well-designed cable management section on the side. There is an additional dust filter for the back of the case, if you do want to pull air in from the back. For my build I use the back for exhaust. I don't need the handle, but it's nice to have it as an option. This is my build so others can see what fits inside -ASRock B860M X Wifi 6E DDR5 Motherboard -Crucial Pro DDR5 32GB -Arctic P14 Pro Reverse A-RGB 140 mm fans (2 installed on the bottom) -Arctic Freezer 36 A-RGB CPU Cooler -Termaltake Toughpower GT 750W ATX 3.1 Standard Power Supply -Asus Dual Geforce RTX 5060 8GB
