The Lian Li O11D Mini V2 Flow is a compact mid-tower PC case with tempered glass, strong airflow, support for large graphics cards, and room for extensive cooling hardware. This review examines its build quality, included fans, radiator support, storage options, cable management, hardware compatibility, and potential drawbacks.
The Lian Li O11D Mini V2 Flow combines the visual appeal of a dual-chamber glass case with a compact footprint and an airflow-focused design. At $99, it is positioned as an affordable option for builders who want to display high-end components without moving to an oversized full-tower case.
It is not a perfect case. The angled bottom fans can interfere with one of the motherboard's lower PCIe slots, and the compact layout provides fewer rear expansion slots than a typical full-size ATX case. Even so, the build quality, cooling capacity, GPU clearance, storage support, and cable-management features make it a strong value.
The case measures approximately 15 inches tall, 16.5 inches wide, and 10.5 inches deep. Its proportions make it relatively compact for an ATX-compatible case, while the front and side glass panels provide a clear view of the internal components.
| Specification | Details From the Review |
|---|---|
| Height | Approximately 15 inches |
| Width | Approximately 16.5 inches |
| Depth | Approximately 10.5 inches |
| Maximum GPU clearance | Up to 400 millimeters |
| Power supply support | Full-size ATX power supplies up to 200 millimeters |
| Included fans | Five non-RGB fans |
| Maximum fan configuration shown | Up to nine fans, including radiator fans |
One of the strongest features of the O11D Mini V2 Flow is its construction. The tempered glass feels solid, the metal panels are sturdy, and the case does not feel flimsy or inexpensive.
This is especially impressive at the $99 price point. Budget PC cases sometimes compromise on panel thickness, glass quality, mounting hardware, or fit and finish. In this case, the overall construction feels closer to what many builders would expect from a more expensive enclosure.
The case includes five non-RGB fans. Two fans are installed on the side, while three angled fans are mounted along the bottom. The angled bottom design directs air toward the graphics card and other internal components.
The smoke test shown in the video demonstrates strong airflow through the case. The included fans also operate quietly, which can be a major benefit for a computer placed on a desk or used in a quiet room.
The case provides up to 400 millimeters of graphics card clearance, which should accommodate many large modern GPUs. It supports both horizontal and vertical graphics card configurations.
A vertical GPU support bracket is included. Depending on the motherboard layout and desired installation, a compatible right-angle PCIe riser cable may need to be purchased separately.
The bottom of the case includes a dedicated opening for routing GPU power cables. This helps keep the cables out of the main display area and creates a cleaner finished build.
The rear of the case includes five PCIe expansion slots. A traditional full-size ATX case often includes seven, but the reduced number is understandable because this is a compact enclosure.
Builders who need several PCIe expansion cards should review the case and motherboard layout carefully. The reduced rear slot count and the angled bottom fans could limit certain configurations.
The case supports several common motherboard sizes:
Although the case supports ATX motherboards, its compact design means builders should confirm the location of the primary and secondary PCIe slots. A motherboard with its main graphics slot directly below the CPU may require the included vertical GPU bracket.
Unlike some compact cases that require a smaller SFX power supply, the O11D Mini V2 Flow supports full-size ATX power supplies up to 200 millimeters long.
This gives builders more power supply options and makes it easier to reuse an existing ATX unit. The rear compartment includes ventilation for the power supply and helps separate power cables from the visible motherboard chamber.
The case includes two drive cages that support traditional hard disk drives and solid-state drives. The review configuration contains two installed HDDs, with additional mounting positions available for two SSDs.
This makes the case suitable for builds that need more than a single M.2 drive. It can support mass storage, media libraries, local backups, game storage, and other high-capacity applications.
The rear chamber provides space for routing power, storage, fan, and front-panel cables. The case also includes Velcro straps and zip ties to keep the wiring organized.
Dedicated cable openings around the motherboard and graphics card make it easier to keep visible cable runs short. The dual-chamber design also allows excess cable length to remain hidden behind the motherboard tray.
The external control and connection panel includes:
The I/O module can be repositioned to the top of the case, which can make the ports easier to reach depending on whether the computer sits on a desk or below it.
The glass and external panels are designed for easy removal. The front glass can be released by loosening a retaining screw, providing open access to the motherboard chamber.
The rear panel also removes easily, giving direct access to the power supply, drive cages, and cable-management area. Easy panel removal is helpful during the initial build and when cleaning or upgrading the computer later.
The removable top section supports up to three fans and a radiator. The build shown in the video uses two radiator fans, with room for another top fan and an additional rear fan.
When combined with the five included fans, the case can support a configuration of up to nine fans, including the radiator fans shown in the review.
The case includes the basic hardware needed for assembly, although a screwdriver is still required.
The O11D Mini V2 Flow offers a lot for the price, but builders should understand its limitations before purchasing it.
| Pros | Cons |
|---|---|
| Strong build quality for the price | Bottom fans can interfere with a PCIe slot |
| Five quiet fans included | Only five rear expansion slots |
| Up to 400 mm of GPU clearance | No built-in fan controller |
| Full-size ATX power supply support | Vertical mounting may require a separate riser cable |
| Good radiator and fan support | Compact layout requires careful compatibility planning |
| Good cable-management features | Dual-chamber design is relatively wide |
The Lian Li O11D Mini V2 Flow is a compelling PC case for builders who want strong airflow, tempered glass, large GPU support, full-size ATX power supply compatibility, and flexible cooling options without spending well over $100.
Its limitations are primarily related to the compact layout. The angled bottom fans, reduced expansion slot count, and possible need for a PCIe riser cable require some planning. For a typical gaming, productivity, or media PC, however, the benefits can easily outweigh those drawbacks.
The case is available in black and white at the same stated price. The reviewer purchased the case personally, and the video was not sponsored.
0:00 This might be the best PC case I have ever owned. It is far from perfect, but the good points definitely outweigh the bad ones, and we will discuss both.

0:29 The case measures approximately 15 inches tall, 16.5 inches wide, and 10.5 inches deep.
It should look good on a desk, where you can display your expensive graphics card, memory, and other components.
0:41 Speaking of graphics cards, the maximum GPU clearance is 400 millimeters, which provides plenty of room.
0:46 The case supports a conventional horizontal GPU position or a vertical mounting position.
0:52 One of the most important and impressive things about this case is its build quality.
0:55 Nothing feels cheap. The glass is solid, and all the metal is sturdy. Nothing feels flimsy, which is impressive for a case at this price point.
1:04 The case includes five non-RGB fans, which is fine with me.
1:09 There are two fans on the side and three fans along the bottom.
1:13 The three bottom fans are slightly angled to improve airflow toward the internal components.
1:22 As I said before, the case is not perfect.
1:24 What about airflow? I will show you a smoke test so you can see the airflow for yourself.
1:51 Once again, I am impressed with the five included fans. They are strong and quiet. I can barely hear them, which is a major improvement over my previous PC case.
2:01 What else comes with the case?
2:02 It includes the hardware needed for vertical GPU mounting, allowing the graphics card to be installed horizontally or vertically.
2:08 It also includes a small toolkit with the required screws and nuts.
2:17 There is a thank-you card, an instruction manual with detailed information, and some additional wiring for RGB equipment.
2:29 That is essentially everything you need to assemble the case, except for a screwdriver.
2:34 One of my favorite features is the glass. It comes off easily.
2:38 The front glass panel is also easy to remove. Release this screw, and the panel pops off to provide convenient access to the interior.
2:48 Now you can clearly see inside the case.
2:50 The side of the case supports a maximum of two fans.
2:54 I like the plates installed around this area because they help direct airflow toward the fans.
2:57 They also give the interior a more finished appearance.
3:02 The side of the case includes the power button, a USB Type-C port, a USB Type-A port, and a headphone jack.
3:08 This control and port assembly can be moved to the top of the case if you prefer.
3:10 The rear of the case includes five PCIe expansion slots. Most larger ATX cases include seven, but this is a compact case, so the reduced number should not be surprising.
3:21 If the motherboard's primary PCIe slot is positioned directly under the CPU, you may need to use the included vertical GPU support bracket.
3:27 You will also need to purchase a compatible right-angle riser cable to connect the graphics card to the motherboard's PCIe slot.
3:34 If your motherboard has a PCIe slot near the bottom, it may be unusable because of the three angled bottom fans. Keep that limitation in mind when planning the build.
3:41 The bottom of the case includes an opening for routing the GPU power cables.
3:46 This provides another way to keep the wiring neat and organized.
3:48 The case is compatible with the following motherboard sizes:
3:55 What about power supplies? Let us look at the back of the case.
3:57 The rear panel comes off easily.
4:01 The back includes ventilation for the internal components and additional ventilation for the power supply.
4:06 The case supports full-size ATX power supplies measuring up to 200 millimeters.
4:11 The case includes two drive cages that support hard disk drives and solid-state drives.
4:16 I currently have two hard disk drives installed.
4:19 You can also install two additional SSDs in the available mounting positions.
4:21 The case includes plenty of Velcro straps and zip ties to keep the cables organized.
4:27 One thing to note is that the case does not include a fan controller. Since the included fans do not have RGB lighting, that is not a major concern for me.
4:32 Reinstalling the rear panel is easy.
4:33 Line the tabs up with the mounting points, slide the panel into position, and press it into place.
4:40 The panel is now secure.
4:40 The fans also have a removable filter.
4:42 The filter slides out so it can be cleaned. Mine is already a little dusty.
4:46 After cleaning it, simply slide it back into place.
4:48 The final feature to discuss is the top of the case and its radiator support.
4:52 To remove the top panel, release the retaining screws. The panel then lifts off.
4:57 The top section can hold up to three fans and a radiator.
5:01 My personal configuration uses two fans and a radiator.
5:05 I could add another fan at the top and one at the rear for a total configuration of up to nine fans, including the radiator fans.
5:11 To reinstall the top, place it back into position and tighten the screws.
5:15 Reattach the front panel and tighten its retaining screw.
5:19 Reinstall the side panel, and the case is fully assembled.
5:22 The O11D Mini V2 Flow is available in white or black, and both versions are priced at $99.
5:27 I have the white version, and my son has the black version.
5:31 This is the Lian Li O11D Mini V2 Flow.
5:35 It is a fantastic PC case that looks great, provides strong airflow, and can hold the major components needed for a high-performance build, including a large graphics card and a full-size power supply.
5:41 It is priced under $100, which makes it a strong value.
5:45 Product links will be listed below the video.
5:48 I purchased this case with my own money, so this is not a sponsored video.
5:52 Finally, I want to thank all YouTube members and Patreon supporters. Thank you for watching.
