Product information

Description

The Chieftec UB-03B-350GPB is a compact Mini Tower computer case in black with an included 350 W power supply. Designed for home and office environments, it supports Micro ATX and Mini-ITX motherboards, accommodates 2.5" and 3.5" drives, and offers modern connectivity including USB Type-C and a pre-installed SD card reader. Its dimensions (207 mm W x 430 mm D x 373 mm H) make it a space-saving option while allowing optional front 120 mm and rear 80 mm fan installation for improved airflow.

Advantages

The case provides a balance of compact size and expandability with support for one 3.5" bay and one 5.25" bay, a pre-installed 350 W power supply, and front USB Type-A ports. Built-in SD card compatibility and USB Type-C support simplify peripheral connections. Optional fan mounts in the front (120 mm) and rear (80 mm) enable targeted cooling upgrades without requiring a larger chassis.

Suitable for

  • Home desktop PCs with Micro ATX or Mini-ITX motherboards
  • Office workstations needing compact, space-saving cases
  • Systems requiring 2.5" and 3.5" drive compatibility

  • Weight: 4.51 kg
  • Colour: Black

How to use

Install a Micro ATX or Mini-ITX motherboard inside the chassis, mount the included 350 W power supply and connect power cables to the components. Fit 2.5" or 3.5" storage drives into the appropriate bays and connect them to the motherboard. If additional cooling is required, install an optional 120 mm fan in the front and/or an 80 mm fan in the rear and connect to available fan headers or the power supply. Use the front USB Type-C and USB-A ports and the integrated SD card reader for peripherals and removable media.

Usage recommendations

For reliable thermal performance, use at least one additional intake or exhaust fan when populating high-power components. Verify clearance for taller CPU coolers and cable routing when installing multiple drives to maintain airflow and ease of maintenance.
