AI Verdict
This Micro ATX case includes a 650W 80+ Gold PSU and four PWM ARGB fans, making it a compact, ready-to-build option for users prioritizing integrated power and cooling.
This case is a situational fit because it provides a convenient all-in-one solution with a pre-installed 650W 80+ Gold PSU and four PWM ARGB fans, ideal for Micro ATX builds. However, the 170mm CPU cooler height limit and non-modular PSU might be restrictive for some users.
If you plan on using a large air cooler or require more flexibility for cable management, look for cases with greater CPU cooler clearance and a modular power supply.

Dimension Scores
The pre-installed 650W 80+ Gold power supply provides an above-average efficiency rating for its wattage.
The four PWM ARGB fans offer speed control, allowing for some adjustment of noise levels, placing it at category average.
Constructed from steel, plastic, and tempered glass, the material choice is standard for its price band, though one user reported issues with standoff holes.
Dedicated cable routing clips are included, but the non-modular nature of the pre-installed PSU can make achieving a clean build more challenging.
Best For
- Builders seeking a compact Micro ATX system with included power and cooling components.
- Users who want to showcase their PC internals through a tempered glass side panel.
- First-time builders looking for a case with pre-installed fans and a power supply to simplify the build process.
Not Recommended For
- Users planning to install full ATX motherboards or larger components.
- Enthusiasts requiring extensive custom water cooling loops.
- Builders prioritizing premium all-aluminum construction.
Watch Out For
- The maximum CPU cooler height is 170mm, which might restrict compatibility with some larger air coolers.
- The pre-installed power supply is non-modular, meaning unused cables will need to be managed within the case, potentially cluttering the build.
- One user mentioned fan cables using SATA instead of the more common Molex, which could be an unexpected wiring challenge.
- A user encountered issues with incorrectly machined standoff holes for a full ATX board, requiring drilling to fit.

What Buyers Say
Many users find the inclusion of a 650W 80+ Gold power supply and four PWM ARGB fans a significant value, simplifying the build process right out of the box. The tempered glass side panel is a popular feature for showcasing components, and the dedicated cable routing clips are appreciated for tidiness. However, some builders have noted that the non-modular PSU requires careful cable organization, and there have been isolated reports of minor manufacturing inconsistencies like misaligned standoff holes.
“Honestly, the included PSU and fans are a lifesaver, but man, trying to hide all those extra PSU cables was a nightmare, my fingers are still sore.”
Common Praise
- The pre-installed 650W 80+ Gold PSU saves money and simplifies component selection.
- The four PWM ARGB fans provide effective cooling and customizable lighting.
- Dedicated cable routing clips make organizing wires easier.
- The tempered glass side panel allows for a clear view of the internal build.
- The case offers a compact footprint suitable for Micro ATX systems.
Common Complaints
- The non-modular power supply leads to extra cables that need to be tucked away.
- Some users found the fan cables using SATA connectors instead of Molex confusing to wire.
- One user reported that some motherboard standoff holes were not correctly machined.
- The 170mm CPU cooler height limit can restrict choices for larger air coolers.
Ownership Tips
- The pre-installed fans, while ARGB, might not be the quietest under load, so consider replacing them if silence is a priority.
- The tempered glass panel attracts fingerprints easily, requiring frequent cleaning to maintain its aesthetic.
- The space behind the motherboard tray for cable management, while having clips, can still feel tight with the non-modular PSU's excess cables.
- The overall airflow is decent for a Micro ATX case, keeping components within acceptable temperatures during typical use.

Buying Guide
When picking a PC case, you need to think about what size motherboard you have, how much power your components need, and how you'll keep everything cool. A case like this one, designed for Micro ATX, means it's smaller than a standard tower, so make sure your motherboard fits. The included power supply is a big deal because it's already matched to the case, but you need to check if its wattage is enough for your CPU and graphics card. Cooling is also crucial; good airflow prevents your parts from overheating and slowing down.
Micro ATX
This refers to the size of the motherboard the case can hold. A Micro ATX case is smaller than a full ATX, meaning it takes up less desk space but also has fewer expansion slots and potentially less room for large components.
80+ Gold
This is an efficiency rating for the power supply unit (PSU). An 80+ Gold rating means the PSU converts at least 87% of the power it draws from the wall into usable power for your PC, reducing wasted energy and heat compared to lower-rated PSUs.
PWM ARGB Fans
PWM (Pulse Width Modulation) fans can have their speed controlled by your motherboard, allowing for quieter operation when your PC isn't working hard and increased cooling when it is. ARGB (Addressable RGB) means each LED in the fan can be controlled individually, allowing for complex and customizable lighting effects.
Alternatives
If you need more room for larger motherboards or extensive liquid cooling setups, search for cases that support ATX or E-ATX form factors. For higher-power systems, look for cases bundled with 750W or 850W 80+ Gold or Platinum PSUs.
