A3-mATX PC Case, 415mm GPU, 360 AIO, Wood Black Mesh (A3X-WD)

Probably my favorite small case. Great build quality, room for expansion, nearly tooless design, and lots of ventilation. Currently have an RTX 3070 and Ryzen 5 3600 in it with a LARGE noctua cooler and it doesn't get hot at all. Even had room for a 3.5" 8TB Backup drive. The wood grain is a really nice touch and looks good with my wood grain desk. Installation was easy and I still have room for expansion if I need it. 10/10, great case.

I bought this case after seeing many people in the Micro Form Factor Reddit rave about it. I bought a Lian Li Lancool II several years ago and found it to be the best case I had ever built in and have been following Lian Li since. This case boasts a beautiful set of wood panels on front that still allow plenty of airflow to enter. The amount of mesh all around the case meant there was plenty of airflow to dissipate heat without cranking the fans which helps keep it nearly silent. The frame of the case even without the side fan mount is extremely sturdy with absolutely no flex. Building in it was very straightforward, directions show how to mount an ATX or SFF power supply and it was simple. Size was perfect for an ATX motherboard but there’s no room for cable management so it took me as a very seasoned PC builder quite a while to get my cable runs situated which isn’t something I’d recommend for someone who’s new to PC building, but is easy for anyone who’s worked in any SFF case and wants the expandability of a Micro-ATX motherboard. Overall for the price I think this is a case I can recommend to everyone, it’s got beautiful aesthetics, high performance cooling, and a build quality that feels like it should cost a lot more.

I recently built a system using the Lian Li A3 and I’m genuinely impressed. As someone who wanted a true m-ATX build without sacrificing looks or quality, this case hit all the marks. The compact footprint is one of my favorite aspects—it fits perfectly on my desk without feeling cramped, yet still offers excellent airflow and clearance for components. Lian Li clearly optimized the space well: there’s room for a full-sized GPU, multiple storage drives, and tidy cable routing despite the smaller form factor. I was worried about space restrictions, but assembly was intuitive and comfortable even for a first-time builder. Build quality feels premium, with solid panels and clean finishes that elevate the overall look. The case stays cool under load, and the included fan support is great for keeping thermals in check. If you’re building a high-performance m-ATX rig and want something that looks great and performs as well as it looks, the A3 is a fantastic choice. Highly recommend for m-ATX enthusiasts who want a balance of size, performance, and aesthetics!

This is a beautiful case. When it is assembled it is unobtrusive, but classy. It seems like extremely good quality, we were able to very easily move stuff around in the case to fit what honestly probably shouldn't have fit. The space is expected for a small form factor build, part of the problem was what we ended up purchasing to put in it. To help others, this is what is in this PC build in the photos: ASUS TUF mATX B860M Plus board I7 processor Thermalright Aqua Elite Liguid CPU cooler 3 fans (This did cause some issues, we would do 2 if redoing this build) MSI MAG A750 750W Power Supply. This said compact, but it was big. This was the tough fit between the fans and the GPU RTX 5070TI GPU (A beast! at first we weren't convinced it would slot down in properly but it did.) Between the fans, the GPU, and the power supply, it was tight!! But it does fit. The airflow is amazing with the fans, and when under use (battlefield 6 anyone?) all temps remained excellent. Like all micro builds, good pre-planning helps a lot. We had 2 m2's to put in, but the expansion slots are under the GPU. This is not an easy take in/take out so buy an appropriately sized m2 and prepare to leave it there for a while. The case came with all the necessary screws and is a great case for the cost, would totally buy this again.

Easy to build in but proper cable management is basically impossible. Hasn't really affected performance for now probably also due to the case having great air-flow management. I wouldn't build in this again for my next PC but I like it for my current re-build

I wanted to shrink down my computer case size, coming from a Corsaid 4000D. I got a Mini-ITX motherboard and I use an EVGA 1000w PSU l, which fit nicely at the front of the case. I installed 3 fans on the top (1x120 and 2x140) and another fan on the side. I use a Noctua CPU cooler with 2 fans. I had to use right-angle adapters for the Motherboard power, usb 3.0 and usb-c headers in order to fit the second fan on the cooler and still be able to close the case. The cpu heatsink was too wide to fit an exhaust fan on the case so I'm relying on the two CPU fans doing that work. The GPU gets all the air from below. Temps have been manageable. I set a system fan curve to keep it as quiet as possible while wearing headphones, until it reaches a certain temperature. This has worked pretty well and I haven't reached temps above 76°c during gaming sessions. CPU is 9800x3D and GPU is RX 9070XT for reference. This case does the job well. It's easy to open and take apart. Cable management is difficult as there isn't much room behind the motherboard but since it's all mesh, as long as you make room for airflow, it doesn't matter as it can't be seen. The wood finish is very nice and hides the mesh behind it well. Power button and I/O at the front is in a good location and they work well. I tested with an external drive and transfered files at decent speeds with no disconnects. I recommend this case if you want to go Micro-ATX and still want to fit a large GPU and PSU.

Wow, I have built my fair share of personal systems over the years and by and far, this was the best quality case I’ve ever used. Cable routing is good, I used an mATX board, full size Seasonic power supply, full sized GPU (RX 5700 XT), Noctua air cooler with one fan (smaller Noctua, can’t remember model) and everything fit fine. The power supply was the only odd thing since it mounted in front of the case instead of the back like I am used to. A bit of a puzzle to figure out based on the manual how it fit but Lian Li provides a bunch of adapters so different sizes of things can be installed. I thought the adapters were necessary so that threw me off until I figured that out. Only thing I didn’t add was two internal SSDs because frankly I didn’t need them and wanted to minimize my cabling. I am using an nvme drive so am good there. I did have to buy two additional Noctua case fans because there are none in this case but they are cheap enough. One on top exhausting and one in the rear, exhausting. The case is quiet, fits on my desk, the wood front looks great and it’s super easy to take the top or sides off if I need to. Recommended!

Great little case. This was my first matx build. This case is very modular and made it easy to route things where I wanted. Love the PSU mounting too! I had plenty of room to spare inside, and outside its way smaller than my old machine.

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

Looks good and spacious for an matx case. Still pending build. Fits perfectly on my TV table. Using it for couch gaming...

🧱 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.

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.

Case eccezionale, non posso dire altro. Piccolissimo (in foto non rende) ma allo stesso tempo decisamente spazioso e comodo da gestire. Esteticamente splendido e internamente molto ben organizzato. Rispetto ad altri case ha il vantaggio di essere estremamente areato, perchè tutti i pannelli sono micro-reticolati, consentendo un ricircolo dell'aria incredibile. Il pannello frontale è di legno vero. Nella confezione viene fornita anche una scatola con una marea di viti, vitine, bulloni, gommini e tanto altro, tutti divisi in sacchettini con la funzione. Consente di montare qualsiasi alimentatore senza problemi, ATX incluso (consiglio di metterne uno modulare per ridurre il numero di cavi. Ho montato un Ryzen 9700x con Geforce 3060ti e le temperature sono eccellenti. Ottima anche la fattura, nonostante sia decisamente "leggero". I pannelli sono reticolati ma robusti, così come il pannello frontale (reticolo e legno).
