- Pillar-less tempered glass front and side panels offer an unobstructed view of internal components.
- The I/O panel can be repositioned from the front to the top, offering flexibility for desk setups.
Cons
- Cooling performance, while capable, can become audibly loud when increasing fan speeds to reduce CPU temperatures.
- The standard version does not include any fans, requiring additional purchases for airflow.
- Only offers 5 PCIe slots, which might restrict certain multi-card or accessory configurations.
- Vertical GPU mounting can lead to riser cable clearance issues with bottom fans, potentially requiring fan removal.
- The bottom dust filter is reported to be loose, though a user found a workaround by rotating it.
Dimension Scores
The 10° slanted bottom design and support for up to a 360mm top radiator contribute to effective GPU and overall system cooling.
While cooling is effective, achieving lower CPU temperatures can lead to intolerably loud fan speeds.
Constructed from alloy steel and tempered glass, with features like anti-sag brackets, it feels robust, though some users noted minor panel gaps.
Includes special brackets for the 24-pin motherboard cable and is optimized for ATX Back-Connect motherboards, simplifying cable routing.
Best For
- Showcasing high-end components with its panoramic glass panels.
- Compact ATX builds where desk space is limited but full ATX PSU support is required.
- Enthusiasts planning custom liquid cooling loops with a 360mm top radiator.
- Builders using ATX Back-Connect motherboards for cleaner cable routing.
Not Recommended For
- Users prioritizing silent operation at maximum cooling performance.
- Budget-conscious builders who prefer pre-installed fans in the base model.
- Setups requiring more than 5 PCIe expansion slots.
Watch Out For
- The bottom dust filter can be 'incredibly loose' if not oriented correctly, requiring users to rotate it for a secure fit.
- If you're using a vertical GPU mount, a chunky riser cable might interfere with bottom fans, possibly forcing you to remove them.
- Some users reported minor panel gaps, specifically under the motherboard shield, after completing their build.
- The front I/O panel is plastic and its finish does not match the metal top panel, creating a visual inconsistency.
- The black version of the case shows finger marks very easily, requiring frequent cleaning to maintain its appearance.

What Buyers Say
The O11D Mini V2 is a compact case that manages to support full-sized ATX components and extensive cooling, a significant improvement over its predecessor. Many users appreciate the unobstructed view provided by the pillar-less glass panels, making it a popular choice for showcasing builds. However, some builders have pointed out minor aesthetic inconsistencies, like the plastic front I/O not matching the metal top panel, and the bottom dust filter being loose if not positioned correctly.
“Man, this case looks sick with all the glass, but seriously, that bottom dust filter just flops around if you don't mess with it, and my GPU almost hit the fans when I tried to mount it vertically.”
Common Praise
- Supports full-sized ATX power supplies, which was a limitation of the original O11D Mini.
- The 10° slanted bottom design effectively improves GPU cooling.
- Accommodates a 360mm radiator at the top, even with ATX motherboards.
- The pillar-less tempered glass panels provide an excellent, unobstructed view of internal components.
- Offers flexible I/O panel placement, allowing it to be moved from the front to the top.
- Includes anti-sag brackets for both horizontal and vertical GPU mounting.
Common Complaints
- Achieving optimal cooling can result in noticeably loud fan operation.
- The standard version doesn't come with any fans, requiring separate purchases.
- Only having 5 PCIe slots can be a limitation for certain expansion cards.
- Vertical GPU mounting can create clearance issues with bottom fans.
- The bottom dust filter is reported to be loose.
- Minor panel gaps and a plastic front I/O panel that doesn't match the metal top panel were observed.
Ownership Tips
- The black finish picks up fingerprints easily, so keep a microfiber cloth handy.
- If you're using an M-ATX motherboard, you can shift it down for more top clearance, which is a neat trick for bigger radiators.
- The included 24-pin cable bracket really helps keep the main power cable tidy and out of sight.
- The case feels more spacious for cable management than its compact size suggests, especially behind the motherboard tray.
- The side intake mount can feel a bit clunky during installation.
Frequently Asked Questions
Does the O11D Mini V2 come with fans?
The standard O11D Mini V2 does not include any pre-installed fans. However, the 'Flow' variant, which costs slightly more, comes with five 120mm reverse blade PWM fans.
Can I use a full-sized ATX power supply with this case?
Yes, the O11D Mini V2 is designed to accommodate full-sized ATX power supplies up to 200mm in length, thanks to its protruded mesh side panel.
What motherboard sizes are compatible with the O11D Mini V2?
This chassis supports Mini ITX, M-ATX, and standard ATX motherboards. It is also specifically optimized for ATX Back-Connect motherboards.
What is the maximum GPU length and CPU cooler height supported?
The case can accommodate graphics cards up to 400mm long and CPU coolers with a maximum height of 160mm.
Can I mount a 360mm radiator in this case?
Yes, the O11D Mini V2 supports up to a 360mm radiator at the top, even when using an ATX motherboard.
Is the I/O panel fixed in one position?
No, the I/O panel is adjustable and can be moved from the front of the case to the top, offering more flexibility for your setup.
Buying Guide
When picking a PC case, you're balancing size, cooling potential, and how much of your build you want to show off. For a compact case like this, check if your big components, especially your GPU and CPU cooler, will fit. Also, think about airflow – how many fans can it hold, and where does the air go? This case is all about that panoramic view, so if you've got RGB components, they'll be on full display.
Volume (45.38L)
This number tells you how much space is inside the case. A smaller volume like 45.38L means a more compact PC, which is great for saving desk space, but it can sometimes make building a bit tighter and limit component choices.
Motherboard Compatibility (ATX, M-ATX, Mini-ITX)
This dictates what size motherboard you can install. ATX is the standard full-size, M-ATX is smaller, and Mini-ITX is the smallest. This case supports all three, giving you flexibility, but an ATX board will fill up most of the main compartment.
ATX PSU Support (up to 200mm)
Your power supply unit (PSU) needs to fit. ATX PSUs are common, and this case supporting them means you don't have to hunt for smaller, often more expensive, SFX or SFX-L PSUs. The 200mm limit is for the PSU's length.
10° Slanted Bottom Design
This isn't just for looks; it's a clever way to improve cooling. By angling the bottom, the case directs more cold air directly to your graphics card, which is often the hottest component in your PC.
Alternatives
If this case is too small for your needs, look for mid-tower cases with volumes over 50 liters that offer more 3.5-inch drive bays or additional PCIe slots. If you want a smaller footprint but still need ATX compatibility, consider cases with a mesh front for direct front airflow.
