Being used to Tower cases I needed to fit this project is a smaller space. I first tried another mATX tower case but it was too cramped.
This turned out to be one of the most flexible and easy to build project cases I've used and it allowed for a variety of component placings along with several removable mounts depending on your needs.
Because of its design it has room for liquid coolers in several configurations as well as several voids for easy cable management.

Best feature: depending on your MB size, you can shift the entire board mounting position and make more space for other peripherals. E.g. I had a mATX MB with only 4 PCI slots so I...view more Being used to Tower cases I needed to fit this project is a smaller space. I first tried another mATX tower case but it was too cramped.

Best feature: depending on your MB size, you can shift the entire board mounting position and make more space for other peripherals. E.g. I had a mATX MB with only 4 PCI slots so I rearranged the mounting slots so I could put a liquid cooler with fans inside at the top - there was plenty of room for this and lots of space for the cable management.

One tip: It comes ready to mount an ATX PSU. Any other size PSU will need brackets changed and an ATX compatible plate for surface mounting.

Great case just make sure you use the right motherboard standoff screws. I used the wrong ones and it really messed me up Great case just make sure you use the right motherboard standoff screws. I used the wrong ones and it really messed me up

Pros: This is a great case, so easy to build in (my first ever PC build) amazing value, especially because of the 3 fans included, love the modularity of it, love the size, great IO, looks spectacular, great airflow, love the fans it comes with because they are so quiet and efficient, has so much space for 4'5 inch and 3'5 drives also great vibration isolation screw hole things, easy to take the case apart because of all of the thumb screws. It even comes with almost organized screws in a modular screw sorting container!

Cons: I've had it for a week and I can't find something bad to say about it

This is an exceptional case with the ability to have 4 3.5” hdd’s it’s perfect for a home server. The quality is top notch and everything is really straight forward to use. Highly recommended.

Just what I was after for my build, large enough to get all my components in easily, great cable management in the rear compartment. Just one thing to mention is that if using a ATX mobo it may not be possible to top mount a radiator depending on the height of the heat sinks on the mobo, luckily there are many mounting options so no a major issue.

This is the second computer I’ve made using this case. It is so adaptable. I love the space at the back for the PSU and cables, you can keep the front very tidy.

The only downside is that the MB is quite high in the chassis unless you switch it to be upside down. This is the second computer I’ve made using this case. It is so adaptable. I love the space at the back for the PSU and cables, you can keep the front very tidy.

Oh my god, I have so much praise for this case its unbelivable. Just finished my first build in this thing, and the airflow is exceptional, it looks amazing, its small enough to stay on my desk and it can fit so much inside. Cons is it has a ugly bottom air filter, and its ditched the mini itx feel of the O11 dynamic, its not realllyyy mini but its smaller than most atx cases. Pros, 3 fans included which is pretty sweet, I can use a ATX psu and it looks nice and clean. Oh my god, I have so much praise for this case its unbelivable.

I picked up the Lian Li O11 Air MINI for its perfect size to fit my setup, but the pre-installed fans are an absolute disaster. Honestly, they completely ruined what could have been a great case.

First off, I was shocked to find that the fans aren’t even RGB or ARGB. In today’s market, that’s almost a given in this price range. But even more disappointing than the lack of lighting is the sheer poor quality of the fans themselves.

The 140mm front fans are the biggest issue. Right out of the box, they’re noisy and rattly, and it’s not just the typical sound of spinning fans – it’s a consistent, irritating vibration sound.

The 140mm front fans are the biggest issue. Right out of the box, they’re noisy and rattly, and it’s not just the typical sound of spinning fans – it’s a consistent, irritating vibration sound. It’s clear that the fans have serious balancing issues, or possibly poor bearings. The noise is so bad that I had to replace them almost immediately because it became unbearable.

The rattling sound isn’t just an occasional noise either – it’s constant and can be heard from a distance, making it incredibly frustrating if you’re looking for a quiet build. The poor bearings or imbalanced design are the main culprits here, as the fans don’t spin smoothly, causing a lot of unnecessary vibration and noise.

Overall, the case itself is solid, and the size is just right for my needs, but the fans are beyond disappointing. If you’re considering this case, be prepared to spend extra money replacing the fans right away if you care about noise levels or even just basic functionality. For the price, this was a massive letdown, and Lian Li really needs to step up their fan game.

I was very quick to replace these fans, but I honestly would have kept them if they weren’t as bad as they are. I would have potentially even considered using them if the noise and imbalance issues were resolved, but as it stands, they’re simply unusable.

This case is soo amazing way better than my old one, the size and shape of the case is good, i lit my 4080 into it, very good case.
i recommend.

Wanted a case like the O11 Dynamic Mini, but saw the temps and lack of ATX PSU support and it threw me off. After a minute of searching, came across the O11 Air Mini; the perfect hybrid of aesthetics and performance. I've had this case for around a month. Works wonders when paired with a nice air cooler, with my CPU idling at around 38c (in my previous case idling at 50c) . Would definitely recommend to somebody who wants that sleek modern look of the O11 without compromise of airflow, cheers PB you've done it again.

Great so far.
Do note the lack of dust filters in the main intakes of the case, and the holes are relatively large. I plan to add 3rd party custom filters for this case. Great so far.
