Lian Li A3-mATX MD Micro-ATX PC Case - White with Modular Design and High Airflow Support

Looks: I’m my opinion, this is the one of the best looking mATX cases on the market. I’m not big on LEDs and prefer subtle looks and this case nails that. Compatibility: The case is surprisingly roomy, however, if you’re fitting high end parts in here be prepared for a fight. It’s a bit fiddly getting the PSU mount in the right place and it took a lot of trail and error to fit everything in. For reference, I’m running a RTX 5080, Ryzen 7 9800x3D and a 360mm liquid cooler. I did have to swap out the fans on the CPU cooler to slimline ones though and I would also suggest running these throughout the build to save space. Noise: The case is surprisingly quiet, sometimes I can’t even tell whether my PC is on or not and it’s sat on the desk right next to me! Airflow: For my needs the airflow is more than adequate, I’m not going to be overclocking and the temperatures are very good, much better than my old setup. Functionality: While it’s not the smallest case on the market (and certainly not console level) I think it’s the perfect size and very light and easy to move around. I will be sticking with mATX in the future.

I wanted something smaller... not mini ITX and not ATX and this is the sweet spot mATX Looks are always subjective I understand that, but this case is sexy, the mix of metal with glass and wood... just perfect (even if had LOT's of inspiration from Fractal). Build quality is amazing, and surprisingly cheap case, it's quite easy to build on if you plan in advance all the components that you want as based on components size changes... I would recommend 10000% for you to get SFX or SFX-L PSU so you have the best room for GPU and AIO (if using AIO). Cable management... you'll need to be very creative, but once you have all installed, the PSU holder can hide most of the cables on the side (never to be seen again). My first Lian Li case, have been NZXT and Corsair user for a while and I understand the hype, good quality at great price. If you want TOP performance for graphics card go for an SFF 5080 so you can still have ventilation intake at the bottom

Great clean modern case that is pretty straight forward to build in. The walnut accent on the front make it look classy without trying too hard to be flashy like other cases. Really well made and feels premium even when all panels are dismantled. 360mm aio fits well with no issues providing you don't have a ridiculous heat sink on the top left of your motherboard (msi pro b850m-p matx board used) Only slightly difficult thing is cable management, but if done right it can look super clean! Only my second build, first being almost 10 years ago, so some youtube videos on this particular case really helps iron out any issues Overall delighted

Great case with alot of quirks that need negotiating with during a build. In terms of space I easily fit a 7900xt Merc in without its support bracket, using the mini one provided in the case to support it at three points. For cooling the Noctua nh-u12 leaves plenty headroom and a dual tower would fit quite comfortably. Frankly the side mounted fan bracket is a bit unnecessary. There is a best order to do things too with mobo, then all the connectors to mobo, then fans, then card was the best procedure for me. The real difficulties came from getting the pannel cables routed and secured down enough to not interfere with the GPU fans and I think it would be a real challenge with a full Fatboy 4 slot card. You'll probably want to use m.2's too as the 3.5/2.5 drive mounts share space where a long gcard would sit. There's maybe space for a 1x pci card above your gcards but most other slots are going to be blocked off if you are using anything larger than a 2 slotter. I went for a SFF PSU too but a standard atx will work out the box and I highly recommend it's fully modular to save space. Cable routing is pretty tough with very few mounting points for cable ties and power cables eith a tidy rats nest likely despite best efforts. Overall a great case though.

I'll start with the Cons: There are no indicator LEDs in this case, this does not affect its function, but, if one has elected to not have their eyes seared by a multitude of RGB lights etc. in their build, there is no way to be sure the PC is switched on until the POST is complete... There is also no reset button (which was obvious from the illustrations, but still worth a mention, just in case! Cable management is virtually non-existent, so liberal use of cable ties is needed to maintain good airflow within. And the Pro's - of which there are many. (So I'll lazily list the best features) Build quality is excellent, as is the finish of all panels. The case is a dream to take apart and reassemble, panels clip off, and the top is held by 2 thumb screws. When assembled the case is very rigid, despite the panels being relatively lightweight. I built with a Mini ITX motherboard, which was an easy fit, the internal cables were long enough to reach connectors on the board, but only just with the internal USB cables, I would think that, if using a Micro ATX board those cables would be far more relaxed and easier to manage. Airflow is surprisingly good when using a 360mm AIO cooler, even without any other additional fans fitted. For fun I have put my AMD R7 7800X3D CPU and Radeon 7900XTX GPU in, the GPU runs cooler in this case than in my full tower - indicating I need to look into airflow with that case! Minor gripes aside, I think this is a great case, it is easy to build in, with some versatility in PSU mounting and has space enough, and sufficient airflow, to cope with a 3 slot full-size GPU. Lian Li have produced a very good case, at a reasonable price, worth buying, in my opinion.

A very high quality case, this case is very adjustable to suit a lot of different layouts depending on what you are going for. A few points to note however..... if you intend to put fans in the bottom, or an AIO in the top they cant be too thick (Arctic P12 pro etc) as space is limited. In the top with thicker coolers/fans it can hit your ram so planning of components is required. Your gpu also cant be too thick and another point to consider is the motherboard....some boards have lower GPU slots than others and the lower slot boards will mean you cant fit bottom fans. For best compatibility, standard thickness coolers and fans, a motherboard with a high gpu slot and a gpu thats not too thick. After that its plain sailing. I haven't finished my build as of yet but im setting it as 3 bottom fans (intake), 3 top fans on a 360 AIO (exhaust) and the rear fan as intake (because the air is constricted quite heavily from the bottom by the gpu). All in all a nice case, not the biggest but I like its smaller size while still fitting most NVIDIA 5080 or AMD 9070XT Graphics cards. I would definitely recommend this case on the premise that compatible components are researched beforehand.

Although I've been building PCs for decades, this is the first time I've actually built an mATX system. I wanted something a bit more elegant and as a living room piece/PC. I wanted to transplant other components like an ATX power supply over. It really is tool-less, and you can break it down in so many ways. Modular to a degree to fit and configure in multiple ways. You have room for 2.5" SSDs in the side and bottom, but this might restrict cooling options. But with a lengthy graphics card, things are getting tight as it is. Thermals within the case seem okay. Right now I'm only using 2x Corsair iCUE LInk RX120mm fans. I think something like this would benefit better from either no RGB, or something like that iCUE Link system where it's one cable to rule them all. System: CPU: R7 5800X Motherboard: Gigabyte Auros B550M Elite RAM: Corsair Vengeance LPX DDR4 3000MHz Graphics card: Gigabyte RTX 3070 Gaming OC Storage: Crucial P310 1TB + Samsung Evo 970 500GB PSU: Corsair RM650

Honestly had a blast building in this case. Easy to open up lots of options for mounting ssds and the power supply. Alot of space for cables and overall just a fun case to build in.

GeForce RTX 5070 12G VENTUS 2X OCを使い、なるべくコンパクトでおしゃれなケースを探していて購入しました。 まったく問題なく設置できました。 ATXケースなどと比べるとやはりギュウギュウな感じはありますが、きっちり入るので問題はないです。 背面の余裕はまったくないので、ケーブル系を背面に隠すような配線はかなり苦労します。 私は一部のRGBケーブルは背面でしのぎましたが、その程度の余裕しかありません。 私は白と黒両方のケースを買いましたが、白は事務機器っぽすぎる、白に最初は感じました。 ケースの前面がウッドパネルだったのでもっと北欧的な雰囲気を勝手に想像していました。 しかし、PCまわりのグッズを全部白で統一したところ、まったく気にならなくなりました。 白のディスプレイ、白のケーブル、白のマウスとキーボード、白のヘッドホン、白の・・・と白にこだわると そもそも白グッズの選択肢が非常に少ないので、1つ1つの白の色味まで考えているときりがないです。

Quite a good case with good ventilation and mounting options, managed to put in two 360 radiators.

Alabileceğiniz en iyi mATX kasalardan biri.

Me agrada mucho, no fue difícil armar en el espacio reducido, tiene muy buena apariencia, le caben muchas cosas, estoy incluso usando un Noctua NH-D15, un PSU ATX y una GPU de 300mm

Looks good and spacious for an matx case. Still pending build. Fits perfectly on my TV table. Using it for couch gaming...
