AI Verdict
This 5L steel ITX case with front USB and Type-C ports is for experienced builders needing a highly portable system with a 1U PSU and GPUs up to 185mm.
This case is a situational fit because its 5L volume and 7.7 x 4.7 x 8.7 inch dimensions make it exceptionally portable, but these same constraints demand specific, often smaller, components like 1U PSUs and GPUs under 185mm. It's a trade-off between size and hardware flexibility.
If this case is too restrictive, look for cases supporting SFX PSUs and GPUs over 200mm to gain more component options.

Pros
- Measures 7.7 x 4.7 x 8.7 inches, allowing it to fit into a backpack for transport.
- Constructed from 1.5mm thick steel for a sturdy frame.
- Includes both USB and Type-C ports on the front panel, connected via a 19-pin 2-in-1 motherboard header.
- Supports CPU coolers up to 55mm in height.
- Comes with two steel vented side panels and an additional 3mm acrylic vented side panel for customization.
- Supports two 2.5" SSD or HDD drives.
Cons
- Requires a separate 19.5cm Dual Reverse Connectors GPU riser cable, which is not included.
- GPU length is limited to 185mm, or 40mm in height (50mm with standoffs), restricting graphics card choices.
- Not recommended for first-time builders due to installation complexity.
- Some users report panels can warp if not handled carefully during assembly.
- Cable management can be challenging in the confined 5L space.
Dimension Scores
The 5L volume and support for a 1U PSU mean it's designed for efficient use of space and power, but GPU and CPU cooler limitations restrict maximum output.
While the case itself doesn't require fans, the small internal volume means component noise, especially from the CPU cooler and GPU, will be more noticeable.
Constructed from 1.5mm thick steel, the frame is sturdy, but some users report panels can warp, indicating potential precision issues.
The extremely compact 5L interior makes cable management a significant challenge, with users noting it can be difficult to avoid cramming cables.
Best For
- Building a highly portable gaming PC for LAN parties or travel.
- Compact workstation setups where desk space is severely limited.
- Enthusiasts who enjoy the challenge of small form factor PC assembly.
- Users who prioritize a small footprint over extensive hardware compatibility.
Not Recommended For
- First-time PC builders.
- Users needing to install large, high-performance GPUs.
- Anyone prioritizing silent operation without careful component selection.
Watch Out For
- The case does not include the necessary 19.5cm Dual Reverse Connectors riser cable for GPU installation, requiring an additional purchase.
- GPU compatibility is restricted to 185mm in length and 40mm in height (50mm with included standoffs), limiting options to smaller cards.
- Some users have experienced issues with the metal panels warping, suggesting the material, while 1.5mm steel, can be susceptible to bending if not handled precisely.
- CPU cooler height is capped at 55mm, which means many popular air coolers will not fit.
- The Type-C port is not connected via a Type-E interface, which might affect compatibility with some newer motherboards expecting that standard.

What Buyers Say
Users frequently highlight the K39's incredibly small footprint, making it genuinely portable for gaming or travel, often comparing it to the size of a dictionary. However, this compactness comes with trade-offs, particularly in component compatibility and the complexity of the build process, which is not for beginners. Some builders noted that while the 1.5mm steel feels sturdy, the panels can sometimes warp, and cable management is a tight squeeze. Despite these challenges, many appreciate the ability to build a powerful system in such a tiny enclosure.
“Man, this thing is TINY, like I can actually throw it in my bag for trips, but seriously, getting everything to fit without bending something or having a cable nightmare was a real headache, and don't even get me started on finding a GPU that actually fits.”
Common Praise
- The 5L size allows it to fit easily into a backpack, making it highly portable.
- Capable of housing a powerful gaming system despite its small size.
- The inclusion of two handles (plastic and leather) enhances mobility.
- Offers good thermal performance even without dedicated case fans due to its vented design.
- The option to swap between steel and acrylic side panels provides customization.
Common Complaints
- The requirement to purchase a separate 19.5cm GPU riser cable adds to the cost and complexity.
- GPU length and height restrictions (185mm length, 40mm/50mm height) severely limit graphics card choices.
- Building in the case is challenging and not recommended for those without prior experience.
- Some users reported issues with panels warping or not fitting perfectly flush.
- Cable management is difficult due to the extremely limited internal space.
Ownership Tips
- You'll spend extra time planning component purchases to ensure they fit the strict size limitations for GPUs, PSUs, and CPU coolers.
- Expect to invest in custom cables or spend significant time managing standard cables to achieve a clean build.
- The portability is a real advantage, but you'll still need a monitor and peripherals at your destination.
- Thermals are surprisingly manageable for its size, but careful component selection (especially CPU cooler) is key to avoiding excessive noise.
- The build process can be frustrating, but the satisfaction of a complete, tiny system is a common sentiment among owners.
Frequently Asked Questions
What kind of power supply does this case use?
It supports FLEX-1U power supplies, with dimensions up to 170x80x40mm.
Do I need to buy a separate cable for my graphics card?
Yes, you need to purchase an additional 19.5cm Dual Reverse Connectors riser cable for your GPU, as it is not included.
What is the maximum CPU cooler height this case can accommodate?
The case supports CPU coolers with a maximum height of 55mm.
Can I fit a full-size graphics card in this case?
No, GPU length is limited to 185mm and height to 40mm (or 50mm with standoffs), so only compact graphics cards will fit.
Is this case easy to build in for a beginner?
No, it is not recommended for novices to install for the first time; prior experience or watching online tutorials is advised.

Buying Guide
When looking at an ITX mini case like this, you're trading raw power and ease of assembly for extreme portability. You need to be super precise with component selection, especially your graphics card and CPU cooler, because every millimeter counts. Don't expect to just drop in any old parts; this requires careful planning and often specific, smaller versions of components. It's a project, not a plug-and-play experience.

Alternatives
If you need more GPU options or an easier build experience, look for ITX cases that support SFX power supplies and GPUs up to 250mm in length, which typically means a case volume of 7-10L.
