Decent case at a decent price
I got this case to host a scientific instrument control PC. 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.

Mildly Challenging to Build in, Very Pretty
Smaller M-ATX case, so naturally it's a bit tougher to build in. 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.

Excellent mATX case with plenty of room
Not a small form factor case by any means, but if you want something compact that can hold an mATX motherboard and full-sized ATX power supply, as well as excellent GPU support and still have room for 3.5" hard drives, this is the case to get. Lian Li makes incredibly easy to assemble cases packed with accessories and this is no different. Installation was a breeze and temps are super low (currently running a 12600K and RX 9060 XT 16GB), as is the noise level. The only downside is the lack of cable management, but if you're buying the all-mesh version, that shouldn't matter too much.

Case Swapped from Lian Li Lancool III to the Lian Li A3 mATX.
Very fun to build in and surprisingly spacious. The clean white aesthetic looks great, and it fits some seriously large components. I was shocked (in a good way) to see that a Noctua D15S (165mm tall) and a ROG Thor P2 1000W (190mm long) fit inside without issue. I also installed a 3070 FTW3 Ultra (2.75-slot card, 300mm long) with no problems. Why the 4/5 stars: I had a tough time removing and reinstalling the top panel due to the thumb screws—I have to press down on the panel to loosen or tighten the rear screws. The GPU support bracket is also frustrating; the thumb screws are hard to turn without pliers because the threading and paint overspray get in the way. This is one of Lian Li’s budget cases, so some compromises are expected. That said, I think the case is excellent overall. I’d love to see Lian Li create a high-end version of this case with fully removable panels, similar to the NCASE M2. I’d rate it 4.5 stars if I could. I do wish the wood version had been available when I ordered mine—but I’m still happy with the purchase.

Slick, quality, easy to access case with included reusable hardware kit.
Pretty slick little case with clever power supply placement and an included reusable hardware kit with dividers (nice surprise!). I love the easy way each panel comes off to gain access. Seems sturdy and I kinda like the clean white look. It's been a long time since I chose a case color other than black.

Everything now fits
I moved my system from another brand small form factor (SFF) case to the Lian Li. The other case was really cramped and I wasn't happy with the amount of cooling from the other case when gaming. I wanted to try one of the newer designed cases that offer more flexibility but are still close to the size of my previous case. I've got a AMD 9700XTX GPU and finding a SFF case that would fit the length of the GPU wasn't that easy. This case is about the same size as the previous one but its a couple of inches longer so I have a bit more room now and can fit additional fans. I have a mini ITX mobo though you can fit a Micro ATX in this case. One problem. My previous system had a shorter CPU cable and it would not reach the PSU from across the case, so I had to order some longer cables which are much nicer anyways. The case is well built and solid. No dings or defects anywhere, high quality construction and solid. They really packed this baby, I had to cut the bottom of the inner case box to slide it out of its box. It was a super tight fit, but packed safely with styrofoam. The case is quite adjustable which allows quite a few different layouts for your parts. I went with the standard horizontal GPU layout and there is a lot of room left over in the case. All the outer panels are removable which made it a lot easier to work on versus my previous case. And one pleasant surprise is that even with more fans, its quieter than my previous system and is no longer having to rev up while playing games. I have the white case and I highly recommend this case.

Great case for my simple build.
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.

Great Medium Form Factor Case for price point
Love this case. However it’s not without flaws. Lack of cable management is my only real complaint. Also the fact I couldn’t get the wood frame version at the time is annoying. Looks great on my desk, fit 360mm aio and 5070TI

Şık kolay sökülüp takılan bir kasa
