Review: 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!
Review: Reddit was right - 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.

### ⭐⭐⭐⭐⭐ Tiny, but cooling well
*by J***D on January 26, 2026*

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.
