Jonsbo D31 Mesh (Mid-Tower ATX/Aluminium Frame with Mesh Front/3x 120mm Fans/Tempered Glass Side) Review

Jonsbo's D31 Mesh has built a strong following among people searching for an affordable case that doesn't feel cheap, thanks to its aluminium front frame instead of the plastic most budget cases use.

It looks and feels more expensive than its price suggests, with a distinctive vertical-strip mesh front that's become one of the more recognizable budget case designs in the last couple of years.

Premium Materials at a Budget Price

The aluminium front frame gives the D31 Mesh a sturdier, more premium feel than most cases in its price range, which typically rely entirely on stamped steel and plastic trim.

Distinctive Design

The vertical-strip mesh pattern has become one of the most recognizable looks in the budget case space, standing out from the more generic honeycomb mesh patterns most competitors use.

Comparison to Alternatives

Against the Lian Li O11 Dynamic, the O11 Dynamic is a dual-chamber showcase design at a much higher price, while the D31 Mesh focuses on a single-chamber airflow layout at a fraction of the cost. Against the Fractal Design North, the North uses real walnut wood accents for its premium look, while the D31 Mesh achieves a similar upscale feel through its aluminium mesh front instead.
