Pros

  • Compact 14.7L footprint, expandable to 16.4L for larger GPUs.
  • Supports triple-slot GPUs up to 356mm with an adjustable PCIe slot.
  • Includes an 850W SFX Gold ATX 3.0 PSU with custom short-length cables.
  • Features a 90° 12V-2x6 PCIe 5.0 connector for improved electrical durability.
  • Toolless panel removal simplifies assembly and upgrades.
  • CPU temperatures reach 70-85°C under heavy load, with CPU cooling comparable to a 240mm AIO.

Cons

  • Max CPU cooler height is 70mm, limiting aftermarket air cooler options.
  • Users accustomed to larger ATX cases may find the internal space restrictive during assembly.
  • Cooling potential may not be sufficient for extreme CPU or GPU overclocking scenarios.
  • Vertical GPU mounting is the only option, which might not suit all preferences.

Dimension Scores

Efficiency & Output8/10

The included 850W SFX Gold ATX 3.0 PSU delivers up to 600W to the GPU and the case layout ensures efficient airflow for superior cooling, with CPU temps reaching 70-85°C under heavy load.

Noise Level6/10

While thermal performance is noted as good, specific acoustic measurements or user feedback on noise levels are not detailed enough to warrant a higher score.

Build Quality8/10

The case features an anodized aluminum shell and users report thick metal panels with matching cutouts and easy toolless access.

Cable Management7/10

The included 850W SFX PSU comes with custom short-length cables and pre-routed cables with reusable ties, simplifying cable routing in the compact space.

Best For

  • Building a compact Mini-ITX system with high-end GPUs up to 356mm.
  • Gamers needing to fit RTX 5080 or RX 9070 XT in a small footprint.
  • Users who prioritize a small desk footprint over horizontal GPU mounting.

Not Recommended For

  • Users planning extreme overclocking of their CPU or GPU.
  • Builders who prefer horizontal GPU mounting or larger ATX motherboards.
  • Individuals needing to install CPU air coolers taller than 70mm.

Watch Out For

  • The 70mm maximum CPU cooler height means many popular aftermarket air coolers will not fit.
  • Despite being described as 'easy to build in for an ITX,' the compact 14.7L volume can still feel cramped for those unfamiliar with SFF builds.
  • While the included PSU has custom short cables, managing additional fan or accessory cables in the tight space can still be challenging.

What Buyers Say

Many users are surprised by how well this compact 14.7L Mini-ITX case manages to cool high-end components, with CPU temperatures staying between 70-85°C under heavy loads. The included 850W SFX Gold PSU and custom short cables are frequently highlighted as making the build process smoother than expected for an SFF case. The expandable frame design is a clever solution for fitting large triple-slot GPUs up to 356mm, which is a significant advantage for such a small footprint.

“Dude, I crammed my massive 4080 in there and the temps are actually chill, the included PSU with those short cables was a lifesaver, totally worth it for the desk space.”

Common Praise

  • Fits large triple-slot GPUs up to 356mm, even with the expandable frame.
  • Included 850W SFX Gold PSU with custom short cables simplifies power delivery and cable routing.
  • CPU cooling performance is comparable to a 240mm AIO, keeping temperatures in check.
  • Toolless panel removal makes assembly and upgrades straightforward.
  • Anodized aluminum shell and thick metal panels contribute to a premium feel.

Common Complaints

  • Max CPU cooler height of 70mm limits choices for aftermarket CPU cooling.
  • Space can still feel constrained for builders not experienced with Mini-ITX systems.
  • Vertical GPU mounting is the only option, which might not be preferred by all users.
  • Limited cooling potential for extreme overclocking scenarios.

Ownership Tips

  • The expandable frame is more useful than it sounds, allowing for GPU upgrades without needing a new case.
  • The pre-routed PSU cables with reusable ties are a small detail but save a lot of frustration during the initial build.
  • The vertical GPU mount means you'll want to ensure good airflow from the side panels for optimal GPU cooling.
  • Despite its small size, the case feels sturdy and well-constructed, not flimsy.

Buying Guide

When looking at Mini-ITX cases like this, you're trading raw internal space for a compact footprint on your desk. You need to pay close attention to component compatibility, especially GPU length and CPU cooler height, because even a few millimeters can make a difference. The included power supply and cooler here are big deals, as they remove two major compatibility headaches.
