Lian Li O11 Air Mini White - Compact Midi-Tower Case with Tempered Glass and Mesh Panels for Optimal Airflow and Cooling

This is a really nice compact ATX case. It's well made and well finished (seems to be powder-coated) and I even managed to cram an AIO CPU cooler and AIO-cooled RTX 4090 in it, with a bit of tweaking, and with room for up to 4 SATA disks (but maximum of two 3.5 inch HDDs), and not too big to sit on the desk rather than a dusty floor. Very happy with it.

First thing to note about this case is the unconventional design, the case is divided into two halves, one side holds the mainboard and GPU and the other holds the PSU, drives and cabling. This means that the case dimensions are a little different to usual as it is lower than most cases (it's only a few centimetres taller than an ATX mainboard) and quite wide. The second thing is the quality, as usual with Lian Li cases, the case build quality is second to none. Fit and finish of the panels is exceptionally good and makes building in this unusual case a breeze. Designed for air-cooled rigs, you can easily fit a liquid-cooled setup in here as the case is extremely modular and allows for various different setups depending on your specific requirements. Although I am an experienced PC engineer with many years experience, building in this case was as straight-forward and easy as I've ever come across.

I have been building PC's since the 1980's, though not so much in the last decade. I remember when a good case was one where you didnt cut your fingers to bits. They have certainly improved and in recent years I have had no complains in general for cases costing half what this cost. This was actually a build using parts left over from my son's recent upgrades, but it was to sit on my desk and I wanted something a bit special, this looked like it may fit the bill.The 'Mini" in the title is clearly relative to some other case by the same manufacturer as it's actually rather large, but I like the cube like design and even though it's larger than I anticipated it's a object of beauty so I do not mind.This is an exquisite high quality product, seriously well thought out and as nice on the inside as on the outside. It occured to me that if Steve Jobs were alive and building a PC.. this is the case he would use, except of course he would remove or disable the fans! Actually the fans are very quiet in normal use, and under heavy load the design really does allow for exceptional airflow.The supplied hardware and manual are excellent also.My only gripe is that the box was damaged and resulted in a small dent in the side that I was able to remove, a bigger and stronger box would have better.. having said that, I live in Ireland and Amazon shipped this from Italy, so it was quite a journey.

This case is great for atx builds but I personally would not use an e-atx motherboard with it as I feel like there would be some clearance issues with the top and bottom mounted fans, also due to the smaller vertical height it is just quite a bit wider that a traditional case and is a bit expensive for the size and features but is very easy to build in and swap out parts due to the tool less panels and meshes andwould definitely recommend this case for anyone looking for good cooling in a smaller form factor 👍

I've added several extra* fans and running a fairly high TDP system (over clocked 5900X and RTX3080Ti on air cooling - NH-D15), but this thing performs really well. I also have two high spec NVME's, two SATA spindle drives and some notoriously hot memory (GSkill Trident 3600C14), so I think this must be at the limits of any AMD system could generate (Intel 11th and 12th green will run hotter though).If ambient temp is below 25C thermals all stay well within range (no throttling), even during extensive benchmarking and gaming... Ambient temp over 35C has caused some problems during prolonged gaming (CPU exceeding 80C).*Extra 140mm and 120mm lower intake and extra 150mm plus 120mm exhaust. Fans are all Noctua with peak speeds of 1200-1350rpm.Noise levels are very good, even compared to my old Corsair 330R Carbide (solid fronted noise suppression case), but I'm running it on Dynamic fan profiles (around 300rpm on all nine fans until CPU exceeds 50C), temps can be controlled by however much sir you want to flow and the noise will be mostly based on the quality of fans you add.I also have one of these cases running a Ryzen 7 2700X and GTX1660S, Scythe Fuma2 cooler and no extra fans - it's very quiet and at the same time, cool enough that I haven't been taking notes :)

Its not ITX, but it is the most perfect small case I've ever built in. It can accommodate full size ATX boards, with almost no wasted space above or below, while still being smaller and more yet spacious than my previous case, the Corsair 280X. The interior layout is extremely efficient, and the build quality is leaps and bounds ahead of Corsair.

Amazing case with plenty of room for almost any build! The modular design truly accommodates endless possibilities in such a compact design! Very impressed!

Excellent case, bought to move my system into as previous case was cheap and intended as a temporary case before moving to a nicer case in the future. Everything was easy to assemble, and the case is very easy to manage cables inside. Would be nice to have a reset button on the front IO panel as they can very occasionally come in useful, but not really a huge deal
