Big bang for small case
Got this case and was excited to put together my own small form factor build. It is super easy to work with. Just keep in mind it is a small case so it is definitely going to give you a bit of a brain puzzle for managing cables and getting everything to fit. If you are going for an ITX board with a AIO on top, I would recommend sticking with a slim variant as I ran into ram clearance issues; I opted to pit it on the side and add 3 exhaust fans on the top to help promote the original airflow design. I currently have a 360mm AIO a 9070 XT GPU an SFX PSU, and managed to still add 6 additional fans inside the case. I use this for my entertainment/VR build and it is doing perfectly fine without issues. Easy to work with, great build quality, love the air flow and room for fans and ease of access with the side panels popping off so easily, but staying locked into place securely at the same time. It also looks great in my living room with the black finish and wood accents. I'd also highly recommend looking at GamerNexus' review of the case to get an idea of how to get the cooling solution right if you are seriously considering this case; they helped a lot with my design choices. *Update* In case anyone is wondering, YES. It DOES fit an Astral 5090. I pulled my 9070 XT out of the case just to fit test and it 100% fits and has room for the 12VHPWR connector adapter.

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.

Easy, high quality, good looking, not too expensive
For too long I kept the old tiny (and ugly as sin) case my PC came with. I stare at it every day. Life is too short for a cramped, ugly PC case, so I got this case. It’s extremely adaptable and user friendly to work in. (I had to move power supply to the side due to the length of cables with my SFX power supply.) Bonus: it looks really nice! The mesh cooling works insanely well. Currently cooling 175 watt GPU + 65 watt CPU (continuous load all night) with a SINGLE 90mm rear exhaust fan (!!!!). [I also had to flip the Noctua Ghost CPU cooler 180 for fit reasons, and I didn’t have extra thermal paste-so I just used the old stuff—NOT ADVISED; just FYI to add context to how well the case is working.]

Great case but bad cable management
If you are not familiar with Amazon Vine, it is basically Amazon trading free* products for honest reviews. You see a lot of Vine reviews that are cookie cutter and based on templates. I aim to make my reviews honest and non-cookie cutter (other than this intro and disclaimer). * These items are not actually free as Vine members pay income tax on the items they receive. Therefore, I will never order something from Vine unless I actually intend to use it. I think this is important for readers to understand because it means I will never order an item just to provide a fake five star review to a company. If I review something as good, it means I actually enjoyed using it or it fills its intended purpose correctly. Items that don't meet my expectations will be reviewed accordingly. Why I ordered this item: I recently built a new audio production computer and wanted it to be a little smaller than my normal builds. I ordered this case because I liked the wooden slats on the front. Likes: * The case looks awesome when loaded with lighting and PC components. The wood adds a very nice touch. * Fan options are super customizable. I have it loaded with eight case fans, which has gone a long way to keeping my build cool. The fan noise level can get loud, but that's more to my choice in fans than this case. * The smaller footprint is awesome. I appreciate that this does not take up a ton of room on my desk. * There are a lot of great internal features. I like how the PS is mounted toward the front. No likes: * The cable management options are awful. I didn't realize it was this bad when I ordered it, or I might not have chosen this case. I was able to make it work and it still looks great, but it took a lot more effort than it should have. Would I pay full price for this product: Yes, even with the poor cable management system I would order this again. I really like this case. Final thoughts: This got the aesthetic I wanted along with the cooling options I needed for under $100. That's a win to me, even if cable management is bad.

Solid Build, Clean Design, but Limited Cable Management
I recently built my PC using the Lian Li A3, and I’m overall pleased with the case. It delivers excellent build quality, a clean aesthetic, and decent cooling, but there are a few things to consider before making your purchase. Pros: Build Quality: The Lian Li A3 has a premium feel with its aluminum construction. It’s solid and lightweight, making it easy to handle and position on your desk. Design: The minimalist design is sleek and clean. The front panel is simple, with a nice look that fits well in any setup. The side panel is a mix of mesh and aluminum, providing a nice balance of airflow and durability. Cooling: While it doesn't have a dedicated front mesh panel, the case still has adequate airflow, especially when combined with good quality fans. The mesh-aluminum side panel does a decent job of letting air flow in while maintaining the case’s clean design. Compact Size: The A3 is a compact case, perfect for users who are working with limited space but still want to fit in full-size components like a standard GPU. Cons: Limited Cable Management: The cable management space behind the motherboard tray is quite tight, which made organizing cables a bit tricky. It’s doable, but not as easy as some other cases that offer more space and options for cable routing. Overall: The Lian Li A3 is a solid choice for anyone looking for a high-quality, minimalist case. While the limited cable management space and the lack of a tempered glass side panel might be drawbacks for some, it’s still a great option for users who prioritize design and compactness over flashy features. If you're okay with a bit of effort in cable management, this case is a great value.

Incredible!
Wow, this case is incredible. It's smartly designed, fits everything, and has great airflow. Instruction book was ok, but it's easy enough to figure out where to put stuff yourself. Kind of like adult LEGOs.

11-Liter SFF Hall of Famer
This case is absolutely amazing, punching well above its weight class. Let's start off with what I have inside mine -- an i7 12700K and am RTX 3090 TUF, powered by a Cooler Master V850 SFX PSU. Man, does this case make it happen. The H2O is able to handle this kind of power because the CPU is liquid-cooled, and the GPU sits on the other side of this sandwich style case. The case itself is rock solid, utilizing a near tool-less snap-together design and plenty of ventilation for its size. It is larger than the previous model (Dan A4 SFX), due to the intention of this being water-cooled. I opted for an MSI CoreLiquid 240R ARGB V2, since the water block is small and offers ARGB. It tames the temps well on my 12700K. You'll need to make sure your AIO will fit in this case, as there are many that won't -- either because the pump/water block is too tall or because the hoses are too thick. You'll also want something that has hoses on swivel elbows. Otherwise, routing the hoses and closing this case will be next to impossible. This was hands-down the hardest aspect of building in this case -- managing the AIO hoses. The A4-H2O gets a lot right. You can cool some higher end CPUs, use a full length GPU, and a semi-pleasant building experience. To top it off, it looks amazing, and the parts are high quality. Just keep your hands off the case, as the finish shows off fingerprints well. This case is an excellent competitor for the NR200, because it's 8 liters smaller, and has nearly all-metal construction. To me this one is the obvious choice. Also in this form factor I would avoid i9 CPUs entirely. They eat up too much power, and make too much heat. My experience with this case has been fantastic, but it did leave me wanting more. Having a liquid-cooled, 11.24-liter PC means it's going to be a tad heavy. It's also too big to fit into my DSLR camera bag. I also think this case's width dimension would be a tight fit in a carry on-size tough case like one from Pelican. If you need a small form factor PC for saving desk space, this is an excellent option. That's the niche this serves for me, and it delivers. Maybe you can make this a portable powerhouse for more than gaming. Its too big and heavy for me. Personally, I've found my 8.1-liter KXRORS S300 case to be a better road warrior, because it fits in my DSLR bag and weighs less. Sure, that one can't be as powerful, but it games very well, albeit a little louder.

High quality and small, super compatible.
This case is a collaboration between DAN & Lian Li, and you can tell. Its really small, really compatible, and was quite easy to build in. Its very simple to cool as well, the mesh allows you to put 3 intake fans on the bottom, and let the mesh handle all the exhaust for you, especially because of the magnetic filter on the bottom of the case.
