  • Pure love! with minor annoyances.
Style: O11 AIR MINI Black
I absolutely love the this case to death after finally being able to build in a o11 based cased i have wanted to get forever and settled on the air mini since i have zero interest in custom water cooling and radiators which to me is a massive waste of time, money and hassle if anything breaks or leaks so i got this case solely for a Air cooled build and i love it so much i find my self just staring at how nice and tiny it is. Swapped all my parts out of a much larger and longer fractal meshify 2 since it took up to much desk space and was mostly empty so i love how compact and clean everything looks in a smaller case and my temps are far far better than what they were in a larger case with the ability to add more fans for airflow and im very surprised i was able to fit my large eatx motherboard in this with basically no real issues so you can in fact fit eatx up to a certain length as they mentioned and have it not affect your cable routing etc. My only gripes and annoyances which are minor and i can get over are the lack of a reset button like my old case which i still don't understand why so many cases are ditching that as it helps me reset my system during a freeze without issue so i really wish this case had one. The other annoyance would be the pci bracket slot covers can be quite tricky to put back in for the last two as i really did have to fight it in order to get the last set of covers back in place so it will frustrate the hell out of you but the overall experience and finish looks is worth the pain. Would highly recommend this case for simple build for the least amount of time and hassle so expect even more of a rough time if you going for the water radiators everywhere route. Also i hope you can lift because this thing is HEAVY when packed full of parts as it was somehow heavier overall then my larger case was and yet i love it. ... show more

  • Great Case, but some frustration.
Style: O11 AIR MINI Black
I absolutely love the look of this case. It strikes a nice balance between being very gamery and still looking like a professional machine. My only real complaint about this case is that it does limit you in how big of a graphics card that you can put into it if you use a front-mounted water cooler. Also, if you opt for a 280mm liquid cooler it has to be front mounted as the top of the case has the holes for it, but the radiator and fans would be mashed against the motherboard. Beyond that, though, the included fans have been great. Nice airflow yet quiet. It's sturdy as all. Breathes very well. Extremely easy to configure the case to your liking and place your components into. Cable routes are easy to use and sensibly place. Lian Li really does make some of the best of the best, and you can tell in all the finer details. Not one sharp corner on the whole thing. ... show more

  • Amazing case, clean look, so much space
Style: O11 AIR MINI Black
PROS - Fits a full size ATX motherboard, 240mm AIO, and a RX 6700XT - It's a STOUT case, my previous case toppled over and broke, this one will not budge at all. - Dual chambered. Airflow is not restricted at all in the front. The power supply sits in the back but is also not affected by the cable management due to it being so roomy. - Beautiful sleek design yet still feels modular. CONS - It's pretty heavy. I like that it won't fall over, but it is in fact a hefty case ... show more

  • Pretty darn good
Style: O11 AIR MINI Black
This case is really nice and easy to build in. It looks great and the airflow is fantastic only a couple minor issues: 1. The included fans have this really annoying buzzing sound which is fine if you don’t plan on keeping the pc on your desk as it is pretty quiet. If it’s staying on your desk, get some fans you know won’t be too annoying. 2. The top and bottom fan mounts are a bit difficult to use if you have 140mm fans and an ATX board. Definitely would not recommend an AIO mounted to the top if it uses 140mm spacing. 3. The vertical gpu mount only works if you have an AIO or a really short air cooler. If you’re running any normal height air cooler (I have a Noctua U12S) just stick with the regular mount. Returning the vertical mount was extremely easy though! Just a typical Amazon return. 4. There was some very minor paint chipping on the corner of one of the panels but that seems like it is shipping damage as the rest of the case looks fine. Would prefer to see better packing foam rather than stiff styrofoam. Over all it is a great case! It fits a full ATX build very nicely with additional space for things like 3.5” HDDs if needed. I would highly recommend this case if you want a slightly smaller build. ... show more

  • Excellent little case
Style: O11 AIR MINI Black
I’ve built three PCs lately (two for my friends, one for me!) and this case has been my favorite. Both of the other builds were in Corsair’s 4000D airflow (which is an excellent case), while I opted for something smaller and more unusual. The build layout and amenities on offer are great, there’s lots of smart cable routing lanes and tie downs, and many of the accessory mounts are painlessly removable. You can also fit in some beefy hardware thanks to a generous main compartment. Temps are a respectable 64c max on my i9-9900k at 5ghz on all cores, after one hour of gaming. 3080ti temps are toastier at 75.9c, with a hotspot of 84.3c. No throttling at max boost clocks though, so I'm happy! All in all a handsome and versatile case with enough modularity to suit my needs. Recommended! ... show more

  • The BEST Small-ish Case
Style: O11 AIR MINI Black
The Lian Li O11 Air Mini is an excellent case all around. Extreme modularity which allows for easy builds, an amazing amount of potential case fan locations, and it even fits a full sized ATX motherboard while being a small case. Cable management is a bit tight, but very manageable. Lian Li also goes above and beyond by including a little plastic case including a generous amount of extra screws and stuff. I’m definitely going to continue supporting this company because of the insanely good products they produce. Although the fans are a bit expensive (not pictured), but thats just me being cheap… they are priced similar to their competitors. ... show more

  • Beautiful Case, Very User-Friendly
Style: O11 AIR MINI Black
I love the sleek design of this mini case by Lian Li. I am in the process of rebuilding my pc and this is my absolute first time building one (only previous exp with any computer stuff is installing hard drives into my pre-built) and decided to go with this case and I’m so happy I did! I have 6 Corsair 120 fans on the top and bottom as well as the three stock fans (that I plan on switching to the colorful ones as well later on) and the airflow inside is amazing keeping my computer at around 50° C. I have a 3080 ti (which does have three small fans as well) installed and it fits perfectly as well. The versatility of this case is amazing as all my parts fit with many more options for others/adjustable points for different configurations. Again, this is my first time building a computer and fitting everything in the case and doing cable management was extremely easy with this case and I would definitely recommend to anyone looking for a clean designed mini tower with good airflow. ... show more

  • Best mini case I've ever seen or used
Style: O11 AIR MINI Black
So this case is amazing. Temps are way better then I expected. I'm running intel and a strix 4080 super meaning even the biggest 4090s could fit in the case. It's tight right near the fan but it kind of helps even that with temps. My cpu runs 55 to 62c full load depending on the activity. My gpu is 61c under full load yet to see it go higher then that. This case is great ans God the black one looks incredible! I'm sure the white one would also. Simple to build in just remember the riser for the micro atx motherboard if you are using an aio so you can put the motherboard lower. This way nothing gets in the way of the aio. Enjoy! ... show more
