Lian li b4 Matx
Just wrapped up a build in the new Lian Li B4 M-ATX, and I have to say… I’m in love with Micro-ATX now.
I’ve always gravitated toward larger showcase builds, but the B4 completely changed my perspective. The clean, minimalist design looks incredible in a setup, and it’s a refreshing change of pace from all the flashy RGB-heavy builds. It feels compact without making any real compromises on high-end hardware.
One thing I really liked is that the case supports a full-size ATX power supply, although I’d definitely recommend going with an SFX unit if you can. It makes cable management much easier and gives you a lot more room to work with.
I was also able to fit an ASUS ROG Astral RTX 5080 and a 360mm AIO in the case, which is seriously impressive for something this compact. The Astral does fit, but you need to be mindful of cable routing. Since the card has a top-mounted fan, make sure to tuck the GPU power cables up and out of the way so they don’t contact the fan.

Overall, this build completely changed my opinion on Micro-ATX. Being able to fit hardware like a 360mm AIO and an Astral 5080 into such a clean, compact case is awesome. I can’t wait to build in more cases like this.
