Entry ATX mid-tower with ARGB lighting

The MasterBox Lite 5 is a steel, plastic and tempered glass ATX mid-tower aimed at first-time builders who want a clean look and addressable RGB illumination out of the box. It accepts ATX, Micro ATX and Mini ITX motherboards and ships with three 120 mm ARGB fans behind a DarkMirror front panel. Three swappable colour trims let you match the exterior to the lighting theme you prefer.

Front-panel airflow and radiator limits

The DarkMirror panel restricts direct intake, so cooling performance depends on the gap around its edges and the three included fans. Radiator support stops at 360 mm in the front with up to 50 mm thickness without a fan, while the rear accommodates only a 120 mm unit. A graphics card up to 400 mm long fits, and a tower CPU cooler up to 163 mm tall clears the side window.

Dual-chamber layout and daily usability

A bottom-mounted power supply chamber isolates PSU heat and hides cables behind a cover, keeping the main compartment tidy. Two internal 3.5-inch bays and three 2.5-inch slots handle a modest storage array, while the front I/O provides two USB 3.2 Gen 1 ports, headphone and microphone jacks, and a dedicated ARGB controller button. The edge-to-edge tempered glass side panel showcases the build without tools.

Questions about this item

Should I pick the ATX, Micro-ATX or Mini-ITX motherboard tray for this case?

All three form factors fit the same tray; choose the board that matches your CPU and feature needs.

What does the 400 mm GPU length limit mean for my graphics card choice?

Any card up to 400 mm long will install without hitting the drive cage or PSU shroud.

The front ports list USB 3.2 Gen 1 — what speed does that actually give me?

It runs at 5 Gbps, the same throughput as the former USB 3.0 label.
