AI Verdict
This 12.1L vertical ITX case fits triple-slot 350mm GPUs and ATX PSUs, designed for compact, powerful builds with compromised GPU cooling.
This 12.1L ITX case offers a compact vertical design and supports large 350mm triple-slot GPUs and ATX PSUs, making it appealing for powerful small form factor builds. However, its thermal performance, especially for the GPU, is compromised due to limited clearance and fan support, making it a trade-off for its small size.
If you need better thermal performance for your GPU, look for ITX cases with more direct airflow paths to the GPU and support for thicker fans or AIO liquid cooling.

Pros
- Compact 12.1L vertical design maximizes desk space.
- Supports triple-slot GPUs up to 350mm, including RTX 4060/4080 models.
- Compatible with ATX, SFX, and SFX-L PSUs, offering power supply flexibility.
- Includes a dual reverse PCIe 4.0 riser cable and a 1.5m DisplayPort 1.4 extension cable.
- Features a side-mounted steel handle and weighs 5.5lbs (2.5kg) for portability.
- Front panel includes 1x Type-C (10Gbps) and 2x USB 3.0 (5Gbps) ports.
Cons
- GPU cooling is compromised, with a 10°C GPU temperature spike compared to an open-air test bench.
- Limited fan support for cooling, only accommodating up to three 140x15mm ultra-slim fans (sold separately).
- Lack of built-in storage mounts, requiring alternative solutions like double-sided tape.
- DisplayPort output clearance issues, where some GPU ports may be blocked by the case base or 90° connectors.
- CPU cooling is limited to air coolers up to 73mm in height.
Dimension Scores
It fits large GPUs and ATX PSUs in a small volume, but thermal limitations hinder peak output efficiency.
The case itself doesn't generate noise, but the need for slim fans and potential for higher component temperatures might lead to louder fan operation.
Constructed from high-density steel and ABS plastic with a scratch-resistant finish, and uses screws for easy disassembly.
While it has some strategic holes, the lack of dedicated storage mounts and tight spaces can make cable management challenging.
Best For
- Gamers or creators needing a compact PC that fits a large GPU on a desk.
- Users who frequently transport their PC to LAN parties, dorms, or business trips.
- Builders prioritizing a small footprint and aesthetic over peak thermal performance.
- Those who already own or plan to use an ATX PSU and want to reuse it in an ITX build.
Not Recommended For
- Users demanding top-tier GPU thermal performance without modifications.
- Builders requiring extensive internal storage options beyond two 2.5" SSDs.
- Anyone needing liquid cooling support for their CPU or GPU.
Watch Out For
- GPU temperatures can spike by 10°C compared to an open-air setup, potentially reducing boost clocks by over 100MHz.
- Only 2cm of clearance below the GPU and 14mm for air to escape, leading to hot air recirculation.
- Some GPU DisplayPort outputs may be inaccessible due to the case base or 90° connectors blocking adjacent ports.
- A complete lack of built-in storage mounts means you'll need to improvise with double-sided tape for 2.5" SSDs.
- Only slim 15mm fans fit, limiting cooling options and requiring specific fan purchases.

What Buyers Say
The L400 Mesh case is a visually appealing, compact ITX option that manages to squeeze in full-length triple-slot GPUs and ATX PSUs, which is a rare combo for its 12.1L size. However, this compact design comes at a significant cost to GPU thermal performance, with some users reporting a 10°C temperature increase compared to open-air testing. The limited clearance around the GPU and the requirement for slim fans mean you'll be sacrificing some thermal headroom for the aesthetic and small footprint.
“Man, this case looks sick on my desk and fits my huge GPU, but my 4080 is running way hotter than I expected, and I can barely plug in my second monitor without a fight.”
Common Praise
- Compact 12.1L vertical design saves desk space.
- Accommodates full-length triple-slot GPUs up to 350mm.
- Supports ATX PSUs, avoiding the need for SFX/SFX-L power supplies.
- Includes PCIe 4.0 riser and DisplayPort 1.4 extension cable.
- Sturdy steel and ABS construction with a modern aesthetic.
- Easy disassembly with screws for modding.
Common Complaints
- Significant GPU thermal performance issues, with temperatures rising by 10°C.
- Very limited clearance (2cm below GPU, 14mm for exhaust) for GPU airflow.
- DisplayPort output blockage by the case base or 90-degree connectors.
- No built-in mounts for 2.5" SSDs, requiring alternative mounting methods.
- Only supports ultra-slim 15mm fans, limiting cooling options.
Ownership Tips
- You'll likely need to experiment with fan orientations (e.g., both fans as exhaust) to achieve the best possible, albeit still compromised, GPU temperatures.
- Consider using 20mm standoffs for the PCIe riser mount if your GPU is a two-slot card to improve clearance and airflow.
- Be prepared to use double-sided tape or other DIY solutions for mounting 2.5" SSDs.
- Custom cables might be necessary for cleaner cable management and to avoid obstructing airflow in tight spaces.
- You might need specific 90-degree DisplayPort adapters or be limited to fewer display outputs due to port blockage.
Frequently Asked Questions
What size GPUs can this case fit?
It supports triple-slot GPUs up to 350mm (13.78 inches) in length, such as RTX 4060 or 4080 models.
What kind of power supplies are compatible?
The L400 Mesh case is compatible with ATX, SFX, and SFX-L power supply units.
Does it come with fans?
No, the case supports up to three 140x15mm ultra-slim fans, but they are sold separately.
Are there any issues with GPU display outputs?
Yes, some users have reported that certain GPU DisplayPort outputs might be blocked by the case's plastic base or 90-degree connectors, potentially limiting usable ports.
How is the cooling performance?
While it has mesh panels for airflow, GPU temperatures can be significantly higher (up to 10°C) compared to open-air setups due to limited clearance and fan options.

Buying Guide
When you're looking at compact ITX cases like this, you're always balancing size against cooling and component compatibility. A smaller case often means less room for airflow and larger coolers, so you need to decide what's more important: a tiny footprint or keeping your high-end components running cool under load.
12.1L Volume
This number tells you how much internal space the case has. For an ITX build, 12.1 liters is quite compact, meaning it will take up minimal desk space but also implies tighter component clearances.
350mm Vertical GPU Support
This indicates the maximum length of a graphics card you can fit. Being able to fit a 350mm GPU, especially a triple-slot one, in such a small case is a big deal, as many powerful GPUs are quite long.
ATX PSU Support
This means you can use a standard, larger ATX power supply instead of being forced into more expensive and sometimes harder-to-find SFX or SFX-L units, which can save you money.
PCIe Riser 4.0
This cable allows you to mount your GPU vertically. Version 4.0 is important because it supports the latest graphics card speeds without performance loss, unlike older 3.0 risers.
Alternatives
If you need significantly better GPU cooling and are willing to sacrifice a few liters of volume, look for ITX cases that support thicker fans, larger CPU air coolers, or even 240mm AIO liquid coolers.
