Computer case Cooler Master QUBE 540 Moonstone — mid-tower with tempered glass side panel (gray)

Cooler Master QUBE 540 Moonstone is a mid-tower computer case in gray with a tempered glass side panel designed for desktop PC builds. The chassis accepts ATX, micro-ATX and mini-ITX motherboards and provides internal space for standard components, including multiple drive bays and expansion slots. The tempered glass side panel highlights installed components while the internal layout supports conventional cooling options and accessible cable routing for clean builds.

Advantages

This mid-tower case combines a neutral gray finish with a tempered glass side panel to offer component visibility without compromising a compact footprint. The QUBE 540 Moonstone supports common motherboard sizes and multiple storage and expansion configurations, allowing straightforward installation and upgrades. The internal arrangement emphasizes airflow and serviceability so users can maintain or swap components with minimal effort.

Suitable for

• Gaming PC builds that require a balance of component visibility and airflow
• Home or small office workstations using standard ATX or micro-ATX motherboards
• System upgrades where easy access to drives and expansion cards is needed

Key specifications

• Form factor compatibility: ATX, micro-ATX, mini-ITX
• Chassis type: Mid-tower
• Side panel: Tempered glass for component visibility
• Color: Gray exterior finish
• Drive bays: Multiple internal bays for 2.5" and 3.5" drives (standard configurations)
• Expansion slots: Several PCI expansion positions for add-in cards
• Cooling support: Space for case fans and conventional air or liquid cooling components

How to use

Install a compatible motherboard (ATX, micro-ATX or mini-ITX) on the internal standoffs and secure it with screws. Mount power supply, storage drives and expansion cards into the designated bays and slots. Route cables through the provided cutouts to keep airflow unobstructed and close the tempered glass side panel to view the installed components. Ensure cooling fans or radiators are positioned according to component clearance and manufacturer recommendations for optimal thermal performance.

Recommendations

For best results, choose components that conform to standard sizes for ATX or micro-ATX builds, use cable ties or straps to secure wiring, and plan fan or radiator placement before final assembly to maintain efficient airflow and to preserve visibility through the tempered glass panel.
