Description
Enhance your computer build using the O11 AIR Mid-Tower Case from Lian Li. Designed for highly efficient airflow and cooling for gamers, enthusiasts, and overclockers, this mid-tower case features a compartmentalized, fully ventilated, front panel for direct air intake. Air is pulled in through the front and bottom and expelled using the top and rear exhaust fans to optimize cooling for critical components such as your GPU, CPU, and motherboard. Two 120mm fans are included with room for one more on the top of the case. Alternatively, they can be switched out for two 140mm fans. The front, side, and bottom panels each support up to three 120mm fans while the rear mounts can hold up to two 80mm fans. As for liquid cooling, you can mount 360mm radiators on the front, top, side, and bottom to completely maximize your cooling setup.
Made using thin and lightweight electrogalvanized steel, the O11 AIR has eight full-size expansion slots alongside three 2.5/3.5″ drive bays, one 2.5″ drive bay, and two additional 2.5″ drive mounts on the bottom. Its drive cage can also be used to hold a second PSU for increased power efficiency and redundancy. The modern style case also includes an easy-to-remove tempered glass side panel that provides a full view of your system’s build. Two USB 3.1 Gen 1 Type-A ports, one USB 3.1 Gen 1 Type-C port, and two separate 3.5mm audio jacks for your headphones and microphone are built into the front panel for easy access.

Great case with ports on the front!
Myron Gottlieb (verified owner) –
High quality. More than enough fans. Overkill air filtering. Room for an extreme liquid cooling system if you want that option. And Excellent cable management system!

COVID really raised the price on this case, that’s the only negative. It was a pleasure to build in this case. It has excellent airflow and tons of room for liquid cooling. I have 3 120mm fans pulling in fresh air from the bottom directly onto my 2080 TI.

This is the first lian li pc case I’ve ever purchased and it truly is a beauty with excellent options available to expand should I require upgrading. Highly recommended!

Build-wise, nothing in this case feels cheap. I have no complaints. Aesthetics-wise, this case looks sleek, clean, professional-esque, and easy to build in. It doesn’t have any of the unnecessary ‘gamer’ look that I avoid (I like keeping the gaming look inside the hood). You can take out all side panels and have ample access to all areas you’d ever like to get to. The panels are easy to remove and replace, with the exception of the front panel. It needs a little TLC and a bit of an oomph to pop off. You need to be careful when removing because of the contact pads that make the connection to the HDD and power light are sensitive. This case is great when it comes to airflow. I have set 6 fans blowing air in (bottom and front), providing positive air pressure to reduce dust from creeping in through the crevices. I have set up a 360mm AIO on the top for the CPU as exhaust. Since I have set the 6 fans as intake, I can set the fan curve to a much lower RPM to reduce noise (you can add 3 more fans on the side and further lower all intake fan’s RPM to further reduce noise if desired). Pay in mind it doesn’t have any noise dampening though. If you leave fan curves to its default setting, you may get unwanted noise results. I also liked the fact that the bottom fans can feed directly to my GPU. Note that when installing the fans, you need to use the flat/flush-type screws to mount it. I have tried using vibration dampening fasteners and it protrudes to the point of not being able to install the air filters. The air filters sit outside the chassis via magnets. The PSU is installed behind the motherboard, leaving more room in the motherboard area. However, pay in mind that due to the way the motherboard is positioned more towards the bottom you may encounter the same difficulty as I had with connecting audio, USB 2/3, and power switch leads, as putting bottom fans can partially block you from easily connecting them. Although doable, I suggest installing the bottom fans first before connecting said connectors. Storage expandability-wise, you have room for multiple storage devices but with a caveat; if you intend to install multiple SSDs on the bottom of the case, you will lose the ability to mount bottom fans. I didn’t mind taking the removable SSD cages out, since I installed 3 m.2 NVMEs on my motherboard already. You have room for 3 HDDs/ and 1 SSD behind the motherboard. Of course, you can fit SSDs in the HDD cages but you may need to purchase additional hardware to do so. Because of the way this case is designed, cable management is great. You can simply tuck every slack of wire to the back of the motherboard and it will not be seen, as long as it doesn’t pass the side fan cutouts.

Great shipping experience case was delivered with no damage and on time and the case is just incredible great cable manegement and a lot of space for creativity I will probably use this case until it breaks first time customer from overseas very happy with my purchase

Best of the 011 variants by far!!! Still for water cooling though, tall tower cpu coolers won’t fit. Put your AIO rad on top, the extra front fans keep my OC’d 3080Ti cool. Need the U power adapters for these big 3080s to fit. Wish the bottom was designed like the top of case, I cut out the bottom mesh and added a rad grill for lower restriction. Throw away those dust filters!! Love the way components fits — superbly engineered. After about 3 dozen hobby builds, this case is tops!!! My 6 Sythe Kase Flex fans are dead quiet at all speeds. Would like an all aluminum model…..

I purchased this case for my RGB-based build for 2020. Lian Li’s cases are highly customizable and very flexible with how you use them – for example, there are at least 9 places you can fit 120mm fans, and those same places can even accomodate 140mm fans. While this is a bit expensive for a computer case, this remains one of the best show off my build cases you can buy – the tempered glass and sturdy construction means it will keep my parts safe for years to come.
