be quiet! Shadow Base 800 Review

be quiet!'s Shadow Base 800 is what shows up when people search for a quiet ATX case that still supports a 360mm radiator, since most silent cases restrict radiator size to keep noise down.

It manages both with an open mesh front and top for airflow and insulation mats on the side panel, so a large AIO can still breathe and you're not choosing between quiet and cool the way you would with older be quiet! cases. The 305mm PSU limit drops to 260mm with a bottom fan fitted.

Acoustic Design

Insulation mats line the side panel, and the included 140mm Pure Wings 3 PWM fans are tuned for quiet running.

Radiator Support Without the Usual Trade-Off

Unlike be quiet!'s older Pure Base or Dark Base cases that often cap front radiators at 280mm to preserve dampening, the Shadow Base 800 supports up to a 420mm front radiator.

Comparison to Alternatives

Against the be quiet! Silent Base 802, the Shadow Base 800 supports a larger 420mm front radiator where the 802 is more conservative, though the 802's dampening is marginally more aggressive. Against the be quiet! Dark Base Pro 901, the Dark Base Pro 901 is the larger, more premium flagship with a modular interior, while the Shadow Base 800 focuses purely on quiet cooling at a lower price.
