The Lian Li O11 Dynamic Mini V2 represents an evolution in design over its predecessor, the O11 Dynamic Mini, where it now supports ATX power supplies and comes with a laundry list of new features such as a slanted bottom fan tray for improved airflow.

On 25 July 2025, Lian Li lifts the veil on its latest addition to the popular O11 Dynamic line-up of PC case offerings: enter the O11 Dynamic Mini V2 (O11D Mini V2). Anointed as the successor to the O11 Dynamic Mini, the O11D Mini V2 features full support for ATX motherboards and power supplies, and comes with a new slanted bottom fan intake panel for improved GPU cooling, all while retaining the brand's characteristic O11D design aesthetic.

Available at a MSRP of $89.99 US dollars (or $99.99 US dollars for the O11 Dynamic Mini V2 Flow variant with five preinstalled reverse blade fans), Lian Li's new dual-chamber case is available in black or white colourways, and builds on the success of the original O11D Mini - it sure has big shoes to fill! Read on to learn more about the O11D Mini V2 and its various improvements over its predecessor, as I take a look at the case and do a demo build using Lian Li's new HydroShift II LCD-C 360R AIO CPU cooler, UNI FAN CL Wireless 120 case fans and UNI FAN SL-Infinity Wireless 120 case fans.

Packaging & Accessories

The O11 Dynamic Mini V2 comes in a brown cardboard box with your usual product illustrations and descriptions on all sides.

A single rectangular cardboard box containing the case's accessories is included; opening up the box, we see that Lian Li's included an expansion slot frame that is to be used for vertical GPU mounting purposes, a vertical GPU support bracket, a translucent plastic box containing bits and bobs such as your screws and what not, as well as an instruction manual.

Opening up the plastic box, we get a whole bunch of screws, cable ties, anti-vibration rubber rings for 2.5” SSD mounting purposes, spare friction clips for the side panel of the case, as well as a thank you note.

A plus point about the user manual, we get illustrations on how best to do cable management with this case – it’ll definitely save end-users some time with figuring out the cable management situation with this case when building their PCs.

Exterior Walkthrough

With the case out of the box, we can catch a good look at Lian Li's characteristic O11 aesthetic, with what the brand terms a seamless corner design with tempered glass panels for the front and left sides. As can be seen, we get a long strip of silicone to protect the edges of the tempered glass panels during shipping.

For this review, Lian Li sent over the black version of the O11D Mini V2, and for those of you thinking of building a white-coloured PC, the O11D Mini V2 also comes in a white colourway too, as per the image above captured from the reviewer's guide sent by Lian Li. It’s worth mentioning that the black variant of the O11D Mini V2 comes with a darker tint for the tempered glass panels, while the white variant comes with clear tempered glass with no tint.

The front tempered glass panel shows the first key difference that the O11D Mini V2 has over its predecessor, that is, a slanted bottom panel for intake fans, which is manifested in this gradient that you can see towards the bottom of the front panel.

The other side panel comes with ventilation openings right above where the side mounted case fans and your power supply unit’s cooling fan would be, where this brings us on to the next tweak that Lian Li has done with the Mini V2...

All thanks to the raised section on the side panel as pictured above, the O11D Mini V2 is now able to accommodate full-sized ATX power supplies, unlike the original O11D Mini where you could only install PSUs in the SFX form factor.

In terms of front panel connectivity, we get a 3.5mm headphone and microphone combo jack, dual USB 3.0 Type-A ports and a single USB 3.2 Type-C port - do note that the case doesn’t come with a power LED or a hard disk activity LED. A feature worth highlighting is the fact that end-users can reposition the front panel I/O module to suit your desk setup - the case comes shipped with the I/O module mounted on the front, closer to the bottom of the front panel, and you have the option of relocating the said module to the top panel of the O11D Mini V2.

The blank filler plate pictured above is removable, and you can relocate the entire I/O module to the top, which is great for you folks who place your PCs on the floor.

To get started with the relocation, you’ll need to remove the drive cages and drive mounting bracket in the side chamber of the case so as to get clear access to the front panel I/O module and its associated cables. Once this is done, you can undo the four screws that hold the I/O module in place, and remove the module from its mount.

Before mounting the I/O module at the top, you’ll need to reposition the cables within the I/O module so that the cables run in a direction that facilitates better cable management - the cables will need to run to/fro the short edge of the module when it's to be installed on the top panel.

Removing the blank filler plate at the top of the case is a breeze, where all you’ve got to do is to undo two screws that hold the plate in place. With the plate out of the way, we can go ahead to plonk the module right in the vacated opening at the top panel, and secure it in place.

With the front panel I/O relocated to the top of the case, you have the option of replacing the blank filler plate to cover the space where the I/O module used to occupy on the front panel, or if you’d prefer, even remove this triangular-shaped faceplate on the front entirely, so as to have improved airflow and to create a recess that makes moving the case around just a little easier.

Repositionable I/O module aside, while we’re on the topic of the top panel of the case, we see that Lian Li has included ventilation openings right above where you’d install your top mounted case fans or radiator.

Over on the bottom panel, we catch a glimpse of the O11D Mini V2's triple 120mm fan openings, where we also get a removable dust filter for good measure. The case also sits on machined aluminium feet with rubber protectors.

Moving to the rear of the case, an immediate characteristic that stands out is the fact that the O11D Mini V2 has just five expansion slot openings due to its compact size - this is noteworthy, as such a design would preclude the use of ATX motherboards that have their primary PCIe x16 slot positioned at the first slot location. Should you have such an ATX motherboard, you'll have to install your graphics card in the vertically mounted position instead with a riser cable.

That aside, an interesting feature to point out is the fact that the O11D Mini V2 supports what Lian Li terms a “High” and “Low” motherboard mounting position.

In this regard, we get a repositionable rectangular plastic cover that comes mounted in the default “High” mode for ATX motherboards, like so.

If you’re intending to install a micro ATX or mini ITX motherboard in the O11D Mini V2, you get the option of mounting the motherboard in the “Low” mode, where doing so gives you support for thicker radiators. To do so, you’ll need to reposition the plastic cover first, and thereafter reposition the motherboard standoffs accordingly before mounting your said micro ATX or mini ITX motherboard in the case.

Removing the panels on the O11 Dynamic Mini V2 is a pretty straightforward affair, all thanks to a tool-less design for the case's panels. The top panel slides out easily once you’ve undone the two thumbscrews pictured above, where as can be seen, we get a preinstalled dust filter on the underside.

Removing the tempered glass side panel involves undoing a single thumbscrew before the said panel can be pried off. The said panel is held in place by magnets, which create a nice soft-close effect of sorts.

The side metal panel is held in place by friction posts and can be pried off with ease – it’s good to see that we get a preinstalled dust filter for the side-mounted case fans' intake openings.

Finally, the front tempered glass panel is also held in place by magnets for a soft close effect, and pops off easily from the chassis.

Cooling Hardware Support

As mentioned earlier, you have the option of purchasing the O11D Mini V2 with or without pre-installed fans, where the variant that comes with five reverse blade fans preinstalled is called the O11D Mini V2 Flow, while the variant that comes without any fans is simply called, you guessed it right, the O11D Mini V2.

For those of you who are not quite sure of what case fan orientations you should have with the O11D Mini V2, fret not, for the diagram above (which was taken from the reviewer’s guide that Lian Li sent) clearly illustrates how you should setup your case fans.

And with that, let's have a look at the cooling solutions that the side panel supports. We get support for up to two 120mm case fans or a 240mm AIO radiator, and you’ll notice that we get two repositionable side fan airflow covers that are used to minimise airflow leakage, thereby improving cooling efficiency.

The two airflow covers are made of metal and snap into place on the side fan mounting frame, and can be placed in any of the three positions as pictured above, depending on your preference and of course the type of hardware that you’ll be using with this case.

Up top, we get openings that support 1) up to three 120mm fans, or 2) two 140mm fans, or 3) up to a 360mm AIO radiator. On the topic of radiator clearances, the O11D Mini V2 supports AIO radiators up to 72mm in thickness when an ATX motherboard is installed in the "High" position. With a micro ATX motherboard in the "Low" position, radiator thickness clearance increases to 92mm for a 360mm radiator; with a 280mm radiator, the clearance figure is 63mm.

A noteworthy feature is the fact that the top panel comprises a removable bracket that makes it easier for you to install your fans or radiator outside of the case when building your PC.

Over on the bottom panel, we get openings that support up to three 120mm case fans, and we also get a removable bracket for ease of installation of these said fans. The fan bracket is held in place on the lower panel of the PC case by two easily-accessible screws.

A new feature that the O11D Mini V2 has over its predecessor, the O11D Mini, is having the bottom fan tray slanted at a 10-degree angle towards the left side of the case. According to Lian Li, this angled design serves both thermal performance and aesthetic purposes – the brand states that this design improves airflow by channeling cool air from the right-side intake directly toward your graphics card, and it also eliminates the need for "traditional" case feet. The angling also allows you to showcase bottom intake reverse blade fans that may have say, LCD screens or an infinity mirror effect to add more visual flair for your PC build.

Finally, over on the rear, Lian Li’s included a single opening that supports a 120mm fan.

Physical Dimensions & Clearances

In terms of physical dimensions, the O11 Dynamic Mini V2 is pretty compact for a dual-chamber PC case that supports ATX motherboards and ATX power supplies, where it measures in at 423.6mm x 273.3mm x 391.95mm.

For those of you familiar with the original O11 Dynamic Mini, the V2 is larger by ~2 litres than its predecessor, all while maintaining relatively similar dimensions. As a result of this slight increase in size, we get support for ATX power supplies, where the original O11 Dynamic Mini only supports SFX power supplies.

For you folks intending to use an air cooler for your processor, do note that the case supports CPU coolers of heights no more than 160mm, according to Lian Li.

For your graphics card, the O11D MINI V2 comes with support for cards with lengths of up to 400mm, and Lian Li’s also included a GPU support bracket mounted on the bottom panel of the case, which is adjustable for height, and can be shifted left and right as well to accommodate wider motherboards.

The case also supports vertically mounted GPUs, and comes with a replaceable expansion slot bracket for a vertically mounted GPU - as can be seen above, the standard horizontal expansion slot bracket comes preinstalled on the case. Do note that a PCIe riser cable for vertical GPU mounting is not included with the case, and you'll have to purchase the said cable separately.

Changing the orientation of the expansion slot openings to suit a vertically mounted GPU is pretty straightforward, and involves undoing and securing just four screws that can be found on the rear of the case.

When installing your graphics card on the vertical mount expansion slot bracket, do note that the graphics card has to be mounted from the second slot onwards, as shown above, so as to avoid any clearance issues with the bottom mounted case fans.

Bottom-mounted case fans are a necessity for a vertical GPU mount setup with the O11D Mini V2, as they’ll serve as a base with which to install the included vertical GPU support bracket. The bracket can be adjusted for height and lateral positioning with a Philips-head screwdriver.

A feature that is fast becoming commonplace with new PC cases is support for motherboards with rear connectors, and the O11D Mini V2 is no exception. This means that motherboards from say, ASUS’s BTF line-up, Gigabyte’s Stealth series or MSI’s Project Zero line-up will be compatible with this case. That aside, while Lian Li makes no mention of support for EATX motherboards, yours truly managed to fit an EATX motherboard (Gigabyte X670E AORUS MASTER) into this case for a demo build - your mileage may vary especially if you have a really large EATX motherboard.

For dual-chamber PC cases, the power supply is usually mounted in the secondary chamber of such cases, and in the instance of the O11D Mini V2, the case supports ATX form-factored power supplies, which is a feature that its predecessor, the O11D Mini did not have support for. The O11D Mini V2 supports PSUs with a maximum length of 200mm - this is for when you do not have the rear 2.5" mounting bracket installed.

With the bracket installed, the amount of length clearance for a PSU drops down to 170.5mm instead.

To help end-users along with the installation of their power supplies, the O11D Mini V2 comes with a removable PSU mounting bracket as pictured above.

Storage Drive Support

If you're intending to install 2.5" and/or 3.5" drives for your PC build with the O11D Mini V2, you'll be pleased to note that the case comes with a 2.5” drive bracket behind the motherboard tray that supports up to two 2.5” SSDs. We do also get two removable drive brackets situated behind the bottom right hand corner of the motherboard tray; the drive cages each support either a 2.5” or 3.5” drive.

The drive cages each come with a swiveling door that can be used to store excess cables for a cleaner build, especially if you do not intend to install any drives in them.

Building a PC with the Lian Li O11 Dynamic Mini V2

The front panel connectors of the case are nothing to write home about, where we get the usual front panel power switch connector, a front panel audio connector, a front panel USB 3.2 Type-C connector as well as a USB 3.0 Type-A connector. I do appreciate the fact that Lian Li has gone with a nine-pin front panel header for the power switch – you can see that of the nine pin openings, only two are populated with leads for the power switch. This really helps with getting the connector hooked up to the motherboard front panel header with ease, and saves you the hassle of fiddling about with a two-pin connector and trying to get it connected to the right pins on your motherboard.

Getting the motherboard into the case was straightforward enough, where the motherboard standoffs are already pre-installed on the motherboard tray for an ATX form factored motherboard. If need be, you can simply use the included motherboard standoff mounting tool to reposition the standoffs. I did however, have to adjust the position of the GPU support bracket away from the motherboard tray, so as to create room for the EATX motherboard that I used for the demo build with the O11D Mini V2 (a Gigabyte X670E AORUS Master, in case you're wondering, and yes, it does actually fit, though once again, your mileage may vary seeing as Lian Li doesn't explicitly mention support for EATX motherboards).

You’ll also want to make sure that you’ve got the plastic spacer installed in the correct position – in this instance for an ATX board, it’ll be in the “High” position, as pictured above.

Moving on, the case fan installation process was pretty smooth. As part of this review, Lian Li sent over three of their new budget-friendlier Uni Fan CL Wireless 120 reverse blade fans, which I used for the bottom intake fans.

For the side intake fans, I didn’t have any additional reverse blade fans on hand, so I made do with the new Lian Li SL-INF WIRELESS 120 fans that were kindly supplied by Corbell Technologies, the official distributor for Lian Li in Singapore.

As can be seen, I’ve opted not to install a rear exhaust fan, as I didn't have on hand a spare L-Wireless receiver for a standalone Lian Li fan on the rear.

The power supply unit installation process was pretty uneventful, where the case could easily accommodate the Cooler Master MWE Gold 1050 V2 ATX 3.0 that measures in at a length of 180mm - the length of the Cooler Master PSU meant that I was unable to install the rear 2.5" SSD mounting bracket.

For CPU cooling, the folks at Lian Li have sent over one of their newest AIO CPU coolers, the HydroShift II LCD-C 360R, as part of this review. The HydroShift II LCD-C 360R model comes equipped with three UNI FAN CL WIRELESS 120mm fans, and installing the AIO cooler required a bit more effort and adjustments owing to the tighter confines of the space up top – it’s a good thing that the top panel has a removable bracket to make installation a little easier. In this regard, you’ll want to make sure that you check the dimensions of your AIO cooler first, so as to ensure that it fits properly in the O11D Mini V2.

For the demo build, I’ll be installing a chonker of a graphics card, the Gigabyte AORUS GeForce RTX 4090 MASTER 24G, which measures in at a sizeable 358.5mm x 162.8mm x 75.1mm, and fits perfectly within the O11D Mini V2.

With the demo build pretty much done, it’s a good time to talk about cable management with the O11D Mini V2. I appreciate the fact that Lian Li has included nine Velcro straps in the secondary chamber of the case, though as can be seen, I didn't use all of them in the interest of time for this demo build. Nonetheless, it's not too bad of a cable spaghetti situation over in the secondary chamber of the case, despite my lack of cable management chops.

Lian Li's also included a nifty 24-pin PSU cable support bracket pictured above, which helps reduce cable strain on said PSU cable, and also helps with cable tidiness too I suppose.

Moving along, I also appreciate the fact that we’ve got a large rubber grommet that is strategically placed on the bottom panel of the case, so as to allow for easy routing of cables from the secondary chamber to the primary chamber and vice versa.

All in all, the demo build is shaping up pretty nicely, in spite of the fact that I didn't do much in terms of cable management.

Completed Demo Build Aesthetics

Thermal Performance

To benchmark the thermal performance of the Lian Li O11 Dynamic Mini V2 PC case, I put together a demo build with the following specifications:

• CPU: AMD Ryzen 7 7800X3D (stock settings, PBO & Curve Optimiser disabled)
• CPU Cooler: Lian Li HydroShift II LCD-C 360R
• CPU Thermal Paste: Stock Lian Li thermal paste
• Motherboard: Gigabyte X670E AORUS MASTER
• Memory: 32GB (2x16GB) GeIL Orion V RGB DDR5 6000 CL38 (DDR5 6000 CL38-44-44-84 1.35V)
• Storage: Lexar NM790 1TB NVMe SSD
• Graphics Card: Gigabyte AORUS GeForce RTX 4090 MASTER 24G
• PSU: Cooler Master MWE Gold 1050 V2 ATX 3.0
• Case: Lian Li O11 Dynamic Mini V2
• Case Fans: 3x Lian Li Uni Fan CL Wireless 120 Reverse Blade, 2x Lian Li Uni Fan SL-Inf Wireless 120
• OS: Microsoft Windows 11 Pro
• Fan Curve: Stock standard profiles

With F1 23’s in-game benchmark, where I ran a five-lap test for around 9 minutes in total, the Ryzen 7 7800X3D processor in the demo build achieved an average CPU temperature of around 62.5°C, while the GeForce RTX 4090 MASTER 24G by Gigabyte achieved an average GPU temperature of 67.5°C, and an average hotspot temperature of 77.8°C. These results were achieved in a non-airconditioned room with a temperature of 31°C. For the purposes of benchmarking, the fan curves were left on their stock Standard settings without any further tweaks.

Conclusion & Pricing

To sum things up, I think that the Lian Li O11 Dynamic Mini V2 is going to be a hit, especially with its price point of $89 US dollars for both the black and white variants, and $99 US dollars for the Flow variants in black or white. Just as a reminder, the Flow variants come with five preinstalled fans - that equates to $10 US dollars for five fans, which must be the deal of the century.

For these prices, you get a well-built fish tank-style dual-chamber case for the money that also performs decently well from a thermal perspective - this is all in a compact package that supports ATX motherboards, ATX power supplies and very large graphics cards to boot. Fit and finishing is good for its price point, and the O11D Mini V2 also comes with a good amount of support for your cooling needs, plenty of nice-to-haves such as a built-in GPU support bracket, support for vertically mounted GPUs, all topped off by a nice list of customisable features and cable management features.

As of the time of writing this article, the O11 Dynamic Mini V2 is available to pre-order from Newegg - if you're intending to purchase this case from your local retailer outside of the United States, you may want to check in with them regarding the O11D Mini V2's availability.
