Lian Li Unveils the New Compact ATX Tower O11D MINI V2 PC Case
LIAN LI Industrial Co., Ltd., a leading manufacturer of chassis and PC accessories, announces the O11D MINI V2, a compact ATX tower that provides expanded hardware compatibility and better airflow with only a 2-liter increase in size compared to the original O11D MINI design. Now supporting full ATX motherboards, standard ATX PSUs, and radiators up to 360 mm, the O11D MINI V2 is also fully compatible with ATX Back-Connect motherboards. It features a 10° slanted bottom for enhanced GPU cooling, support for both standard and vertical GPU mounting with included adjustable anti-sag brackets, and a repositionable I/O module for flexible front panel ports and button access. The Flow variant of the O11D MINI V2 comes pre-installed with 5 x 120 mm reverse-blade fans, offering optimized airflow straight out of the box.
Minimal Size, Maximum Support
With only a 2-liter increase in volume, the O11D MINI V2 delivers significantly expanded compatibility. Thanks to a subtle side panel protrusion and an offset mounting bracket, the case now supports full-sized ATX power supplies without increasing its overall width. Internally, it accommodates ATX, microATX, and Mini-ITX motherboards, including ATX Back-Connect motherboards, while offering clearance for radiators up to 360 mm at the top and 240 mm on the side. The case supports up to three 120 mm fans at the bottom, two 120 mm fans on the side, one 120 mm at the rear, and up to three 120 mm or two 140 mm fans at the top, giving builders greater flexibility for high-performance configurations.
[Editor's note: Our in-depth review of the U11D Mini v2 is now live]
Optimized GPU Cooling and Mounting Flexibility
The O11D MINI V2 enhances GPU cooling with a newly designed 10° slanted bottom fan tray that directs airflow more effectively toward the graphics card for improved thermal performance. Whether users prefer a traditional horizontal setup or a vertical display for their GPU, the case supports both mounting options and includes dedicated adjustable anti-sag brackets for each configuration. The vertical mount bracket is positioned above the bottom fans and features a screw-based height adjustment to ensure precise alignment with GPUs of varying sizes. (PCIe riser cable sold separately.)
Relocatable I/O for Enhanced Flexibility and Airflow
The O11D MINI V2 features a modular I/O panel that can be mounted at the top or bottom of the case, allowing users to access ports more easily based on their setup. When installed at the top, the bottom of the case can be blocked off or left fully open, increasing airflow potential from the underside to help with GPU cooling and improving case portability.
Availability
The O11D MINI V2 is available on July 25, 2025, at an MSRP of $89.99 for the black or white version, and $99.99 for the O11D MINI V2 FLOW pre-installed black or white version with 5 x 120 mm reverse-blade PWM fans.

It's a bird....
It's a plane.......
Nope, it's............yet ANUTHA boring AF, same ole same same, no-design-effort-whatsoever rectangular boxen....
Oh my, I'm sooooo excited, I could just sh*t myself, hahahaha :D

Remember that PC case manufacturers are heavily constrained by contemporary component standards. Motherboards come in certain dimensions with mounting screw holes in very specific locations (ATX, mini-ITX, etc.). The rear I/O panel dimensions are pretty well fixed. There are guidelines for CPU socket placement, power cable requirements, m.2 drives, PCIe slots, CPU cooler headroom, 120mm/140mm fan mounting locations, 120mm/140mm radiator/AIO mounts, PSUs (ATX & SFF), GPUs, etc. Mount points for 3.5" HDDs, 2.5" SSDs, etc.?
It's not like there are motherboards that are 100mm x 750mm on the market or GPUs shaped like a Borg Cube.
Sure, the external chassis could be shaped into an amorphous blog or some other non-Euclidean shape but that would increase cost due to manufacturing challenges. It's also less practical for the end user to set up, maintain, and support. A typical rectangular box is pretty easy to manufacture, assemble, ship, stock, and configure. Something whimsical like a pig snout containing a couple of USB ports in the nostrils could be added but to what level of consumer appeal would this have?
Or they could design a rectangular box with some snap on decorative exterior panels for a more artistic look that adds zero functionality. Mainstream companies did this 20-30 years ago. More bulk with no additional functionality, just aesthetics. Hell, SGI did this in the Nineties with their graphics workstations: Indigo, O2, Octane, etc. Is that what you want? Do you think there's a good market for that today in 2025 -- one that dried up two decades ago?
Hell, Sony probably could have made PlayStation 5's COGS about 20 dollars cheaper if they just turned it into a bland rectangular box like Xbox Series X.
Of course the manufacturer could offer a custom case design and fill it up with proprietary components giving the buyer scant choice. Dell does that quite well. So does Apple.
These sort of customizations would have more commercial prospects if one is working off a standard mass market product, like a PlayStation or Xbox. But consumer PCs? How many of the people here own the same PC case?
And remember that these themes you mentioned are all copyrighted and trademarked. You want to make Batman-themed PC case skins? Well, you need to convince the Walt Disney Company that it'll be worth it for them to license out the IP to you. And you're not going to do it by claiming you can sell several hundred PC case skins.
Nintendo can easily market limited edition Zelda-themed gamepads and Switch consoles because THEY OWN THE IP.
Walt Disney Company won't come after an individual who uses their 3D printer to put a Batman face relief on their personal custom PC case. In the same way they won't go after some kindergarten kid who scribbles The Joker with fingerpaints. However they will sic their lawyers on anyone who tries to sell one of these custom works.
Same with sports team logos, fast food chains, your favorite snack, Elvis Presley's face, Ferrari's prancing pony, whatever.
But enough of this blathering.
The Lian Li O11D Mini was a very highly rated case and quite popular in its initial form. Lian Li took an opportunity to make this already good case even better. Why is anyone complaining? Lian Li is setting the bar higher, they are setting peoples' expectations higher. That's a good thing. Now if you didn't like the original case, this is just an iterative improvement. We get it, you don't like this particular case.
But that's like bitching that the 2026 Ford Mustang is once again not a six-seat minivan or a 4-cylinder econobox.
If you don't like this particular case, that's your choice. But why sound like a complete dorkwad with zero social graces? And if someone is trying to be funny, well, it's a pretty lame attempt at humor. Worse, it just makes this Q&A forum look like some sort of padded cell for maladjusted weirdos.
Hell, if Nike comes out with a new sneaker that I don't care for, it's not like I log into some sneaker discussion forum and start griping. Why are PC nerds the weirdest sounding people on the Internet?
As to the case thing bleeurgh, not really serious idea, people need to get used to the idea that a case is a case, they are all mostly gonna look the same. the only way to get anything different is to make your own, there are plenty of people that have. Now you just have to fine a case from whomever you like and whatever suits your needs.
I have already got a O11D mini v2 favourited and will be buying one as soon as the funds materialise, gone are my days of massive towers like my previous 7000D air
