JONSBO D41 Mesh Black ATX Computer Case for ATX/M-A.TX Mainboard/RTX 4090(335-400mm) GPU 360/280AIO Power A.TX/SFX:100mm-220mm Multi-Tool Free Design, Black

This is by far my new favorite case. I have always liked smaller computer cases for a good micro ATX build, but then I started to get better parts, and my 4090 and 360mm aio required a pretty large case. I saw this pop up the other day, and had to give it a try. It is just awesome. I wedged a Asus Prime x670e, Ryzen 9 7900x3d, an MSI Gaming Trio X 4090, 3 Noctura fans, a Corsair 360mm AIO, and a 1000w EVGA power supply in this thing. It all fit, the wiring took some planning, but the results are basically a high end pc in a micro atx sized case. This looks so much less bulky on my desk than the fractal meshify 2 or the lian li o11 dynamic. Those cases were huge and this looks tiny by comparison. Performance wise, almost identical to those cases. I'm not seeing any more heat, nor are my fans running louder. While gaming my gpu is around 65 degrees, and my cpu around 57 degrees. Even while stress testing with Aida64, my cpu is only hitting around 75c with PBO on. Really a brilliantly made case.

My Jonsbo D41 build: Core i9-13900K Gigabyte Aorus Elite AX (ATX) 64 GB DDR5 MSI Ventis RTX 3060 Ti OC (2 fan) Corsair 750e modular PSU (ATX) 1 TB WD Black 850x (OS drive) (2) 2 TB Kingston KC3000 (project drives) Arctic Freeze II 360 AIO Specced these parts for a photo/video editing rig. The case does not come with any fans ($100, duh). I prefer this anyway so I can choose my own. I put three Noctua 120mm fans on the bottom to feed the 360mm AIO in a classic chimney airflow. Keeps everything nice and cool even during high loads. Seriously, this thing sits under my desk and I still get 5.8 GHz on the i9-13900K. Cinebench score of 39,496 with hottest core @ 93C. D41 fit and finish are very good. No sharp edges. Paint is even and complete inside & out. Glass - not acrylic - side panel. Tool-less dissassembly. Really well thought out configuration options to accomodate GPU's, AIO radiators, etc. One of the better looking $100 cases out there. Wish I had gotten the add-on screen. Very happy with this case.

It is a well made case, painted well, with good fitment, has no sharp edges and requires no more than a Philips screwdriver to build in. It is about as small as a full ATX case can be and still accept a large graphics card and a 360 AIO. Part of the reason it is small is that the PSU mounting does not require a wasteful bottom compartment. Instead, the PSU is put into a space that is typically not utilized. So the space utilization is very good. It seems clever. But one thing I didn't like was that with a roof mounted 360 rad, the PSU hot air output feeds into the 360 rad which reduces the AIO effectiveness. You can easily build a shunt/partition that will direct the PSU air to the front mesh panel (cardboard/tape would work). Unfortunately such a shunt affects the air path to AIO rad. Also the lid on the roof is meshed but fairly finely. Likewise the floor has a mesh that obstructs the floor fans. The inlet sides of the floor fans are close to the floor mesh and consequently noisier. The end result is that IMO, the design has unnecessary airflow restrictions, this matters a lot when case size (and hence surface area) is reduced but the amount of heat energy that must be vented is still high. This can be partly compensated for with higher fan speed but results in more noise. So it is well made case, small is size due to good space utilization, easy to build in but with air flow issues that result in more noise. For me, the noise was the deal breaker.

Generic case maker designs a case that has unique design copied from other brands. Except they elect to use poor quality metal which is both flimsy and easy to dent / bend. No included fans come with this case, another missed opportunity compared to other generic brands. Ultimately, I wanted this case for the size, it fits a full size ATX motherboard, 360 AIO, and ATX power supply in a compact form factor mostly found in Micro-ATX or ITX cases. In an effort to make their brand stand out, they created an optional LCD display which plugs into an available HDMI port on the back of your computer. They could have made this completely USB-C based with an integrated USB-C to HDMI connector and use a split USB-C front panel motherboard cable to keep the case clean. I wouldn't recommend this case based on cost - as the quality doesn't warranty it.

The thing that sold me on this case was the compact size for a bottom intake fan layout. It’s full ATX, but it’s as compact as a mid-tower for my MATX set-up. Great airflow all around (the reason I got it was for more direct airflow for my gpu fans which helped lower my junction temps by at least 15 degrees). The metal is solid, which is great and surprising for the price range, because typically manufacturers cheap out on flimsy aluminum (this is good build quality). The downside: there is barely room for good cable management in the back of the case (I didn’t upload a pic because I don’t want to be judged)… sacrifices were made, but at least it’s out of sight. All in all I’m giving it a solid 4.75/5 (5/5 for Amazon’s purposes, but that cable routing layout needs to be re-evaluated by the design team.)
