Micro-ATX case for compact builds

The GAMEMAX Defender MB is a Micro-ATX chassis that also fits Mini-ITX boards. It comes with four pre-installed 120 mm ARGB fans and a tempered-glass side panel. Builders who want a smaller footprint without giving up liquid-cooling support will find the layout practical. Buyers who need E-ATX motherboard support or more than five expansion slots should look elsewhere.

410 mm GPU clearance decides fit

The case accepts graphics cards up to 410 mm long when the front cover is used without extra fans. That single dimension determines whether a long RTX 4000 series card will install without modification. If your card exceeds that length you will need a different enclosure.

16 lighting modes and proprietary fans

A top-panel LED button cycles through 16 lighting modes with 30 total play-through options including RGB, breathing, single colour and light off. The included ARGB fans are proprietary to this case so replacements must match the same connector and form factor.

360 mm radiator support top and front

Both the top and front mounting points accept radiators up to 360 mm, giving flexibility for AIO placement. Dust filters on the bottom, right side and top cover help keep the interior clean during operation.
