Because it is designed for micro ATX and Mini-ITX boards, the B4-mATX Mesh keeps the overall build compact without forcing you into the tightest small-form-factor layouts. Choose the motherboard size that matches your needs, from a minimal Mini-ITX setup to a more expandable micro ATX configuration.
The case ships without a power supply, so you can pick a unit that matches the wattage and efficiency your components require. This gives you full control over the build and makes it easy to reuse a PSU you already own when upgrading.
This white Mini Tower case suits home and office desktops, compact gaming systems and first-time builders working with micro ATX or Mini-ITX hardware who want a tidy, light-coloured setup.
