Product information

Description

Cube PC Home/Office chassis designed for micro ATX and Mini-ATX motherboards, offering support for both 2.5" and 3.5" hard drives. The case includes multiple internal bays and an anti-dust filter, finished in black for a neutral appearance suitable for home or office environments.

Advantages

The chassis supports compact micro ATX and Mini-ATX systems while providing bays for both 2.5" and 3.5" drives, allowing flexible storage configurations. An integrated anti-dust filter helps reduce dust ingress and maintain component cleanliness. Its black color provides a discreet, professional look that fits various setups.

Key specifications

  • Form factor compatibility: micro ATX, Mini-ATX
  • Supported HDD sizes: 2.5", 3.5"
  • Number of 2.5" bays: 2
  • Number of 3.5" bays: 2
  • Feature: Anti-dust filter
  • Color: Black
  • Intended use: Home / Office (Cube PC)

How to use

Install a micro ATX or Mini-ATX motherboard into the case following the motherboard and case manual. Mount 2.5" and 3.5" drives into the corresponding bays and secure them with screws or tool-less mounts if available. Connect power and data cables from the power supply and motherboard to each drive. Ensure the anti-dust filter is positioned correctly and clean it periodically to maintain airflow and reduce dust buildup.

Recommendations

Regularly clean the anti-dust filter and internal components to prolong hardware life. Verify motherboard dimensions and internal component clearances before purchasing additional large cooling solutions or long graphics cards to ensure compatibility with the cube-style micro ATX / Mini-ATX case.
