AI Verdict
This 11L Mini ITX case with 4mm aluminum and a 20mm walnut base offers adjustable internal layout for specific GPU and CPU cooler clearances, ideal for a compact, air-cooled build.
This case is a situational fit for SFF builders seeking a premium aesthetic and air-cooling focus. Its 11L volume and adjustable internal layout allow for powerful hardware, but the trade-offs between GPU length and 3.5-inch HDD support, plus the lack of liquid cooling options, mean it won't suit every compact build.
If you need more flexible cooling or storage, look for SFF cases with dedicated radiator mounts or more drive bays that don't compromise GPU length.

Pros
- The 4mm aluminum shell and 20mm black walnut solid wood base provide a premium tactile experience and structural rigidity.
- Three adjustable motherboard levels allow for optimizing GPU thickness (up to 3-slot) or CPU cooler height (up to 78mm) based on component selection.
- Multi-faceted mesh panels on three sides are designed for efficient heat dissipation.
- Tool-free installation with clipped aluminum panels and sliding side panels simplifies assembly.
- Includes a PCI-e Gen 4 riser cable, supporting modern graphics cards out of the box.
- Integrated base with hidden wiring contributes to a clean aesthetic.
Cons
- Graphics card length is restricted to 202mm if a 3.5-inch HDD is installed, limiting storage and GPU options simultaneously.
- The spine's three fixed adjustment locations offer less granular control over internal spacing compared to some competitors.
- No dedicated provisions for liquid cooling radiators, limiting advanced cooling setups.
- Cable management can become challenging, especially when using larger air coolers that might overhang RAM modules.
- Front I/O is limited to a single Type-C port, lacking additional USB-A ports.
Dimension Scores
The multi-mesh panel design and adjustable internal layout allow for efficient air cooling of components, with a reported 300W GPU running in the 60s Celsius.
With a 300W GPU, the case reportedly kept noise levels to 40 dBA, indicating effective thermal management without excessive fan speeds.
Constructed with 4mm aluminum panels and a 20mm black walnut wood base, the case exhibits precise tolerances and a premium feel.
While the base hides some wiring, the sandwich layout and potential for large air coolers to obstruct RAM can make internal cable management difficult.
Best For
- Building a compact, air-cooled gaming PC with a powerful GPU up to 310mm.
- Users prioritizing a premium material finish and a minimalist desktop aesthetic.
- Enthusiasts who enjoy a tool-free assembly process and component flexibility within an SFF footprint.
Not Recommended For
- Builders requiring extensive internal storage with multiple 3.5-inch HDDs.
- Systems planned with custom liquid cooling loops or large AIO radiators.
- Users needing numerous front panel USB-A connections for peripherals.
Watch Out For
- Installing a 3.5-inch HDD reduces maximum GPU length from 310mm to 202mm, forcing a choice between storage capacity and graphics card power.
- The spine's three fixed adjustment points for motherboard position might not perfectly align with every component combination, potentially leading to unused space or tight clearances.
- While tool-free for panels, internal cable routing can be difficult, particularly with a large CPU air cooler that may obstruct RAM and cable paths.
- The included PCI-e riser cable is Gen 4, so if you're planning a future-proof build with a Gen 5 GPU, you'll need to upgrade the cable.

What Buyers Say
Since the official release date is in the future (September 3, 2025), widespread consumer reviews are not yet available. However, early access reviews highlight the case's premium materials, like the 4mm aluminum and 20mm walnut base, and its tool-free assembly. The adjustable internal spine is a key feature, allowing builders to prioritize GPU thickness or CPU cooler height, though it has only three fixed positions. Builders should be aware of the GPU length limitation when using a 3.5-inch HDD and the lack of liquid cooling support.
“Man, this case looks sick with that wood base, and it actually fits my big GPU, but I had to ditch my old hard drive for it. Building in it was mostly easy, but those cables were a nightmare to hide!”
Common Praise
- The 4mm aluminum panels and 20mm black walnut wood base feel high-end and contribute to a visually appealing build.
- Tool-free panel removal with stiff clips and a leather tab makes accessing components straightforward.
- The adjustable spine provides flexibility for fitting either a thicker GPU or a taller CPU cooler.
- Effective air cooling performance, keeping a 300W GPU in the 60s Celsius without excessive noise.
- Dust filters on each panel help maintain internal cleanliness.
Common Complaints
- The three fixed positions for the motherboard spine are less flexible than continuously adjustable designs found in some other SFF cases.
- No options for installing liquid cooling radiators, limiting thermal solutions for very high-end components.
- Installing a 3.5-inch HDD significantly reduces the maximum supported GPU length.
- Cable management can be a tight squeeze, especially around larger CPU air coolers that might interfere with RAM.
- The included PCI-e riser cable is Gen 4, which might require an upgrade for future Gen 5 graphics cards.
Ownership Tips
- The aluminum panels, while tool-free, are very stiff to remove initially, requiring a firm pull on the leather tab.
- The integrated base effectively hides some cables, contributing to a cleaner desk setup.
- Dust filters on all mesh panels are a practical addition for long-term system maintenance.
- The limited front I/O means you'll likely rely on rear motherboard ports for most USB devices.
Frequently Asked Questions
What kind of power supply does this case support?
It supports SFX power supplies, with a maximum length of 100mm.
Can I install a large graphics card in this case?
Yes, it supports graphics cards up to 310mm in length, but this is reduced to 202mm if you install a 3.5-inch hard drive.
Does it come with a PCI-e riser cable?
Yes, a PCI-e Gen 4 riser cable is included. Jonsbo states it will upgrade to PCIe 5.0 in 2026.
What is the maximum CPU cooler height?
The maximum CPU cooler height is adjustable in three levels, ranging from less than 58mm to less than 78mm, depending on the motherboard position setting.
Does this case support liquid cooling?
No, there are no specific provisions for liquid cooling radiators in this case. It is designed for air cooling.
Buying Guide
When looking at a Mini ITX case like this, you need to think about what components you're actually putting inside. It's not just about the case's size, but how it handles your CPU cooler, graphics card, and storage. Small cases often mean compromises, so know your priorities before you buy.
Volume (11L)
This tells you how much space the case takes up on your desk, like comparing a shoebox to a backpack. 11 liters is quite compact, meaning it's designed for minimal desk footprint.
A4 Compartment Structure
This refers to how the components are laid out inside, typically separating the motherboard/CPU from the GPU. Think of it like a sandwich, where components are on either side of a central spine, which helps with cooling by giving each major heat source its own air path.
Adjustable Motherboard Levels
This is a clever feature that lets you shift the motherboard's position. It's like having adjustable shelves in a cabinet; you can make more room for a really thick graphics card or a taller CPU air cooler, but not usually both at their maximums.
SFX PSU Support
SFX power supplies are smaller than standard ATX ones, which is crucial for compact cases. They're like the compact car version of PSUs, allowing for more internal space for other components, but they can sometimes be more expensive per watt.
Alternatives
If this case doesn't fit, look for SFF cases with more flexible internal layouts, such as continuously adjustable spines, or those with dedicated 240mm/280mm radiator support for liquid cooling, and more generous drive bay options without GPU length compromises.
