Fantastic case
Very pleasant design for living room gaming. Fits in well in my tv cabinet. Its not the smallest, but has plenty of space for component and to let them breath. There are many combinations of fan and PSU positions, which is good For the price, its an amazing case. The mesh panels allow for decent cooling and the mesh design means the airflow does not make much noise

Small, elegant, still spacious.
Although I've been building PCs for decades, this is the first time I've actually built an mATX system. I wanted something a bit more elegant and as a living room piece/PC. I wanted to transplant other components like an ATX power supply over. It really is tool-less, and you can break it down in so many ways. Modular to a degree to fit and configure in multiple ways. You have room for 2.5" SSDs in the side and bottom, but this might restrict cooling options. But with a lengthy graphics card, things are getting tight as it is. Thermals within the case seem okay. Right now I'm only using 2x Corsair iCUE LInk RX120mm fans. I think something like this would benefit better from either no RGB, or something like that iCUE Link system where it's one cable to rule them all.

Good case, finicky usb c front header
It’s a good case for the price. All reviews praise it but I found it to be a bit hard to place full size psu with the cables. Also usb c front header cable does not go in the motherboard well. Might be an issue with the motherboard but for now it does not work. If you pick this machine you are solving for good case on the budget, it’s hard to go wrong with this case but also can wait for its successor (b4). Easy to build, going with only air cooling the space was plenty airflow is good with cheap 120 mm fans.

Great pc case
I personally love this case because it's sleek, and looks nice and professional with the wood panel on the front. The air flow in and out of the case is good just check your GPU measurements before buying to see if it will fit. Also I would highly recommend getting slim fans if you have an larger GPU. Overall I have loved this case and would buy again if I had the chance

Great SFF case with quirks to handle in the build.
Great case with alot of quirks that need negotiating with during a build. In terms of space I easily fit a 7900xt Merc in without its support bracket, using the mini one provided in the case to support it at three points. For cooling the Noctua nh-u12 leaves plenty headroom and a dual tower would fit quite comfortably. Frankly the side mounted fan bracket is a bit unnecessary. There is a best order to do things too with mobo, then all the connectors to mobo, then fans, then card was the best procedure for me. The real difficulties came from getting the pannel cables routed and secured down enough to not interfere with the GPU fans and I think it would be a real challenge with a full Fatboy 4 slot card. You'll probably want to use m.2's too as the 3.5/2.5 drive mounts share space where a long gcard would sit. There's maybe space for a 1x pci card above your gcards but most other slots are going to be blocked off if you are using anything larger than a 2 slotter. I went for a SFF PSU too but a standard atx will work out the box and I highly recommend it's fully modular to save space. Cable routing is pretty tough with very few mounting points for cable ties and power cables eith a tidy rats nest likely despite best efforts. Overall a great case though.

I love this case!
I absolutely love this case and will probably stick with it forever. I wanted the black wood version, but I'm not paying a scalper. The white has grown in me. It's a very flexible and easy case to build in, even for a first timer like me. The sides come off with a quick snap and it comes with all the hardware. The only thing that might be an issue is that the entire case is mesh, which is great for cooling, but not for dust. Only time will tell if dust becomes an issue with this case.

Gran compatibilidad.
Me agrada mucho, no fue difícil armar en el espacio reducido, tiene muy buena apariencia, le caben muchas cosas, estoy incluso usando un Noctua NH-D15, un PSU ATX y una GPU de 300mm

Boîtier compact, propre et agréable à monter 🖥️
🧱 Très belle qualité de fabrication : ce Lian Li A3 mATX donne tout de suite une impression de sérieux. Les panneaux s’ajustent bien, rien ne couine, rien ne force, et l’ensemble fait vraiment “boîtier premium” plutôt que tour bas de gamme légère et branlante. 🔧 Montage simple et bien pensé : l’intérieur est assez malin pour un format micro-ATX. On a la place de travailler, de passer les câbles proprement et d’installer son matériel sans avoir trois mains. Même avec plusieurs SSD / HDD et une carte graphique correcte, on arrive à garder quelque chose de propre. 💨 Bon potentiel de ventilation : il n’y a pas de ventilateurs inclus, mais les emplacements prévus permettent de se faire une config adaptée à ses besoins (flux d’air orienté silence ou perf). Une fois mes propres ventilateurs installés, la circulation d’air est bonne et les températures restent raisonnables. 🎛️ Format compact mais polyvalent : le volume est contenu, ce qui est parfait pour un bureau qui manque de place, tout en restant assez large pour ne pas se limiter à des composants “mini”. C’est un bon compromis entre compacité et confort de montage. En résumé : ✅ Les plus : design sobre, qualité perçue, intérieur bien pensé, gestion des câbles correcte, bon potentiel de refroidissement une fois équipé. ⚠️ À savoir : aucun ventilateur n’est fourni, il faut prévoir le budget en plus et savoir un minimum ce qu’on veut comme flux d’air. ⭐ Au final, pour un boîtier micro-ATX compact, agréable à monter et bien fini, je suis vraiment satisfait : 5 étoiles méritées.

Satisfaction is guaranteed
Incredible case. Love the mounting options for the PSU and the fact that it’s open mesh from all sides. I fitted one exhaust fan and the temps are so good even while using an air cooler for the CPU. It looks nice, sleek, and the wood accents are nice. Highly recommended.
