Things to Consider

  • Cable management can be tricky in such a compact layout, especially when using an ATX PSU with many cables. - Only the top panel supports a radiator; front radiator mounting is not possible, limiting water cooling options. - Some extra-long ATX PSUs (over 160mm) may not fit; always check PSU dimensions before purchasing. - Competing cases in a similar price range (e.g., Fractal Design Pop Mini Air) offer different strengths like noise damping or tool-less design, so consider your priorities.
