AI Verdict
This Micro ATX mini tower with a pre-installed 400W non-modular PSU and 240mm AIO support is for budget office builds or systems using low-power components.
This case is a situational fit because its compact size and pre-installed 400W non-modular power supply are suitable for specific low-power, budget-conscious builds. However, these features become significant limitations for any system requiring more power or efficient cooling.
If you plan on using a dedicated graphics card or a more powerful CPU, look for a case with a higher wattage (550W+), 80 PLUS certified, modular power supply and an open mesh front panel for better airflow.

Cons
- The pre-installed 400W power supply is non-modular, complicating cable management.
- Front panel airflow is restricted by a mesh over small holes, leading to higher temperatures.
- Max GPU length is 280mm and max CPU cooler height is 150mm, limiting component choices.
- Front I/O panel only includes 2x USB 2.0 and 1x USB 3.0, which is limited for modern peripherals.
- Some users report coil whine from the pre-installed power supply.
Dimension Scores
The pre-installed 400W power supply is non-modular and lacks an 80 PLUS rating, limiting its efficiency and suitability for many modern components.
Some users have reported coil whine from the included power supply, indicating potential noise issues.
Constructed from alloy steel, but user feedback mentions some quality control issues with mounts and screws.
While the case claims 'great cable management,' the non-modular 400W PSU makes organizing cables more challenging in the compact interior.
Best For
- Building a basic office PC with integrated graphics.
- Housing older, low-power components for a secondary system.
- Entry-level systems with efficient CPUs and no dedicated GPU.
- Users on a strict budget needing a case and power supply bundle.
Not Recommended For
- High-performance gaming PCs with power-hungry GPUs.
- Systems requiring extensive cooling for overclocked components.
- Builders who prioritize silent operation due to potential PSU coil whine.
Watch Out For
- The front panel's restrictive mesh significantly hinders airflow, potentially causing components to run hotter.
- The included 400W power supply is non-modular, making cable routing difficult and potentially leading to a cluttered interior.
- Some users have experienced coil whine from the pre-installed power supply, which can be audibly distracting.
- The maximum GPU length of 280mm and CPU cooler height of 150mm means many modern, larger components will not fit.
- Quality control issues on mounts and screws have been reported by some users, impacting the build experience.

What Buyers Say
Many users bought this case for its low price and included power supply, often for building systems from spare parts or for basic office use. The biggest recurring issue is the restricted front panel airflow, which users say causes components to run hot, with some suggesting removing the front panel for better cooling. The 400W PSU is frequently mentioned as a limiting factor for modern gaming builds, and some buyers reported coil whine from it. Despite these drawbacks, its compact size and ease of build are noted for specific, less demanding applications.
“Look, I got this for a cheap build, and it works, but man, that PSU hums and my CPU runs hotter than I like because the front barely breathes. Should've just bought a case without a PSU.”
Common Praise
- The pre-installed 400W PSU saves money on a separate purchase for budget builds.
- Its compact size is suitable for Micro ATX and Mini ITX motherboards.
- The case is described as easy to build in for its category.
- Offers multiple drive bays (one 3.5", three 2.5") for storage options.
- Includes one pre-installed 120mm fan, providing out-of-the-box cooling.
Common Complaints
- Front panel airflow is severely limited by a restrictive design, leading to poor cooling performance.
- The 400W power supply is often insufficient for modern gaming graphics cards.
- Some users experienced coil whine from the included power supply.
- The non-modular power supply makes cable management difficult and messy.
- Limited space for larger GPUs (280mm max) and CPU coolers (150mm max) restricts component choices.
Ownership Tips
- The 400W PSU quickly becomes a bottleneck if you try to upgrade to a mid-range dedicated GPU.
- You might need to remove the front panel or add more fans to get acceptable temperatures, especially under load.
- Cable management is a pain with all the non-modular PSU cables crammed into a small space.
- The limited internal space means you have to be very careful about component dimensions, particularly for graphics cards and CPU coolers.
- The front USB 2.0 ports feel outdated when most peripherals use USB 3.0 or higher.

Buying Guide
When looking at PC cases, you need to think about more than just where your parts go. The power supply wattage directly impacts what graphics card and CPU you can use without issues. Airflow is crucial; if your case can't move air efficiently, your components will get hot, which can reduce their lifespan and performance. Also, check the physical dimensions for your graphics card and CPU cooler to ensure everything fits.
Wattage (PSU)
This number tells you how much power the included power supply can deliver. Think of it like the engine size in a car; a bigger engine (higher wattage) can handle more demanding tasks (more powerful components) without struggling.
Motherboard Compatibility
This ensures your motherboard physically fits inside the case. Micro ATX cases only fit Micro ATX or smaller motherboards, so you can't put a larger ATX motherboard in this specific case.
Cooling Method / Fan Support
This indicates how well the case can keep your components cool. More fan mounts and support for liquid coolers mean better heat dissipation, which is like having a good radiator in your car to prevent overheating.
Alternatives
If this case doesn't fit your needs, search for cases with a higher wattage (550W+), 80 PLUS certified, modular power supply, and a mesh front panel for superior airflow.
