Great configurable case
This is a fantastic micro ATX PC case.I really recommend this case, it's amazing how much your can fit in to such a small and good looking case.This case is excellent quality, and a good price. It comes with a box of screws for mounting all the various items in it, has adjustable locations depending on what you want to put in the case and the walnut front adds a certain aesthetic.Follow the instructions for whatever layout you want and it's easy to create your ideal layout. The whole case is a mesh (including the bottom) so the air flow is great. I installed a MSI core liquid 360, motherboard, PSU, 3 SATA drives, 3 extra slimline case fans and my system stays lovely and cool during gaming sessions.Recommended.

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 goodFor 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.System:CPU: R7 5800XMotherboard: Gigabyte Auros B550M EliteRAM: Corsair Vengeance LPX DDR4 3000MHzGraphics card: Gigabyte RTX 3070 Gaming OCStorage: Crucial P310 1TB + Samsung Evo 970 500GBPSU: Corsair RM650

Lian-Li quality in a compact form
I made the decision to upsize my pc case from Sandwich layout SFF cases to a more traditional style layout. I didn’t want anything huge as would still be using my existing mini ITX motherboard.At 26 litres, the case is still compact but a lot larger than what I have been recently used to.The build quality is of the usual high Lian-Li standard. However, the case isn’t as easy a build process as the top and bottom cant be removed. This would have made accessing/installing components much easier. The other gripe is that cable management isn’t as good as it could be. My ATX 24 pin power and EPS cables were quite short and cant be tied down.I’m glad I paid extra for the wood panel front. It adds a really nice aesthetic touch that the plastic fronted version does not.I recommend this case for a compact Micro ATX build. You can fit a lot of high end hardware in this and the build quality is excellent.

Excellent value
Fantastic little case. A bugger to build in but the results are worth it.Fantastic value for the money.

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.

Stylish value
Great value for money and very stylish. Able to fit a 360mm AIO in the top although don't get anything too thick as it won't fit. I'm using an SFX power supply so I had to get extensions for the 24pin and 8 pin motherboard cables. Fits a 3 slot GPU.Looks very stylish with the wooden front panel.

M-ATX Build with GTX 5080 and Ryzen 9800x3d
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!

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.

Compatto, molto spazioso, robusto, esteticamente impeccabile.
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).
