This is distinct from a gaming build: we don't want raw power, just reliability. No giant coolers or GPUs here, so it's quite spacious while simultaneously being nice and compact. I got the simple white version. It's not going to wow anyone with its aesthetics, but it is decently attractive and matches the color of the instrument. It wasn't the easiest case I've ever assembled, but by no means was it difficult or challenging. It's well made and solid: I have no concerns about anything coming loose or being damaged in shipping. One thing I don't love is how the PSU is mounted internally, with the case supplying its own power switch. I prefer to use the PSU's own power switch directly, but we're splitting hairs here. In the end, it's not enough of a problem to remove a full star. Last but not least, the placement of the front USB ports at the bottom of the case is not ideal for a small desk. Can't think of anything else that needs to be said here... it's a decent case at a decent price. I'd use it again.

With that being said, if you have some experience building computers, or can watch you tube, you'll be fine. The build quality is superb, airflow is obviously great, and it just looks good. managed to cram a 3 fan 4070ti super in just fine. ### ⭐⭐⭐⭐⭐ Great case for my simple build. *by J***4 on September 21, 2025* This Lian Li case is the perfect fit for my build. I watched many build videos for this case and decided on ordering it but wanted a black one but it wasn't available at the time. I was a little scepticle if I would like the white one but after building in it it looks great on my desk. 1 fan under the video card and 2 exhaust up top (center and rear) and it cools well. Not much room for cable management but doesn't matter as you can't tell through the ventilated side panel. Glad I got the white. Simple build with Ryzen 3600 and GTX 1060. Stock wraith cooler looks good though ventilated panel. Great case. ## Frequently Bought Together - Lian Li A3-mATX-26.3L Micro Form Factor Chassis-Flexible Power Supply Installation-No Fans Included-Supports 360mm AIO-Modularity Design-For M-ATX and ITX Motherboard-DAN Collaboration-White (‎A3W.US) - Samsung 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
