The Case So Good I Bought It Twice
AKA: The Micro-ATX Marvel With Airflow for Days and Looks That Slap You know how rare it is to find a case that: Looks minimalist and clean without being boring? Has actual mesh airflow that doesn’t choke your fans? Doesn’t feel like it’s going to warp the first time you mount a GPU? Yeah. The JONSBO D31 MESH SC nailed it. And I liked it so much, I picked up a second one—because when a case just works, you stop experimenting and start building. The layout is tight but intentional—everything fits where it should, no cable management rage quits, and the airflow path is dialed. I’ve got one build running a Ryzen 5 5600 with a 240 AIO top-mounted, and the second with a full air tower cooler and a 3060 Ti—both run cool and whisper quiet. What I Love: Full front mesh = unrestricted airflow and dust filtering without killing the look Compact micro-ATX footprint but still fits full GPUs and AIOs—yes, even 2.5–3 slot cards Side window is clear and clean, not tinted black like you're hiding something PSU shroud is clean and smart, giving you that cable-free look even if you didn’t try that hard 😅 Great white finish—not that cheap glossy stuff; it’s clean and modern What Could Be Better: The included fans are basic—not terrible, but you’ll want to upgrade if you care about acoustics or ARGB Clearances are tight if you're trying to squeeze in a thick radiator and tall RAM—measure first Front panel I/O could use a USB-C, but not a dealbreaker for me TL;DR: The JONSBO D31 MESH SC is hands-down one of the best airflow-first, aesthetic-friendly micro-ATX cases on the market. It’s clean, compact, and just makes sense. If you want a case that won’t fight your parts or your build process—and still looks sleek on your desk—this is it. You bought two? Smart. I’d do the same.

Very nice but simplistic
When I saw this case I was like woah screen built in and when I got it. Found that it is removable even cooler if you don't want the screen or want extra cooling. The case is a very simple design in it of itself and without the screen it will look like a regular simplistic PC case. But still nice looking in its own right. But what drew me to the case is the screen itself and at this price point that's not bad at all. Now the case itself. The quality is pretty nice , light, sturdy and some cable management but not very much but it's not hard to put it together at all. The case has a tempered glass side panel with mesh on the top bottom and front of the case for airflow so you don't have to worry about anything choking. Now the screen the screen build quality pretty good and when I took it out the PC case I was surprised by the quality itself especially for this price point. It has a USB type c and a mini HDMI cable to connect to your PC. It has a power button and a brightness up and down button. The resolution looks crisp and bright in the case. I love it personally lol. Now my initial cons of the case are very little cable management. Other than that everything's good so far.

Great tower that looks really nice.
Really nice tower that was easy to set up. It's very open on the top, bottom, front, and back so air flow works well. The screen on the front is nice as well, though I was never able to figure out the diagnostics they wanted me to put on the screen in the instructions.

Beautiful case, lots of air flow, limited space
This case is a very good looking design with a lot of features. The monitor is more of a novelty that I would say I don't personally use a lot but it's a cool feature to have. The mesh panels on the front and top allow a lot of air to keep parts cool and there is plenty of room for most gpus. I currently have a 3 fan RTX 3080 in this case and a 280mm AIO. The power supply is an 850W and I ran into a space issue with the front fan (120mm) mounting just because the size of the power supply. The psu cage is adjustable with about 4 different spots but if you want a fan in the front then the highest psu spot just barely fits to allow a fan. Also for spacing, there is very little room for any cable management on the back side on the case so I wouldn't recommend running an rgb hub. Ultimately, this is a great case. Definitely pleased with Jonsbo and the product they have so far!

Recommend for small pc build
Very nice pc case, love the small form factor. The mechanism to remove the glass side panel and back panel is very nice and easy as it hooks in at the bottom and the top connects with magnets. The only complaint I have is the top panel of the case has thumbscrews, which is the only panel that has screws for some reason, that are pretty finnicky and needs to be removed in order to shut off the psu. Case requires good cooling since its smaller of course but it is just the right size to fit all of your standard pc parts aside from the motherboard as the case only supports m-atx. You can fit standard atx power supplies even ones on the longer side given that your gpu isn't too long aswell. Building in this case isnt hard or bad either and would probably be a cake walk if you get a short atx psu and cable extentions.
