Style: A3 (Wood Front Panel-Black)
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!

From the moment you lay eyes on it, this PC case impresses with its stunning design. The wood finish is truly exceptional, exhibiting a rich texture that catches the light beautifully, while the polished stainless steel components shine with remarkable clarity. The deep, dark shade of black perfectly complements the warm tones of the wood, creating a striking visual harmony. Its size strikes an ideal balance—not too large or bulky, making it a perfect fit for any setup. Assembly is a breeze, with clear instructions that make the process straightforward and enjoyable. Beyond aesthetics, this case excels in functionality, featuring superior heat dissipation and strategically placed ventilation areas that ensure optimal airflow. There’s ample room inside, preventing the components from feeling cramped or overcrowded, which not only enhances performance but also simplifies future upgrades. Overall, this PC case is a well-crafted masterpiece that is worth every single penny.

Nice and compact, easy to install parts, possibly the best airflow for cooling you could get, huge area for a big gpu (fit a 3 slot 4080 super expert lad an example) , and lots of places to mount fans. Pretty happy with it, but I’m a bit disappointed by the lack of places to cable manage. I get that the back is mesh for airflow and adding too much room in the back might make it bulky, but I’d be nice to have places to route the wires and at least some room in the back to hide cables. As a side note, would’ve liked a place to mount at least a 120mm fan to the front, as it’s a perfect way to get more airflow. Also, fair warning, don’t get a 360mm AIO, as you won’t be able to mount it on top with the psu holder in the way. I’d recommend either a tower cooler or 240mm AIO at the most (or at lag leasing an AIO you can mount at the bottom of the case without worry of bubbles reaching the pump).

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!

Amazing case - fit a microATX Gigabyte motherboard, 5070, and everything needed to keep it cool. Easy to install, and amazing looking for the office - more like a piece of furniture. Dust does get pretty thick on top, but a quick vacuum once a month and it's good to go.

This case is a delight for my build, I love the look. A blessing and a curse here, however- the case has no solid panel siding; what I mean is that everything is mesh. Any errant drop of water or something similar and your pc is cooked. Airflow is great on this though, my pc stays cool on just air.
