Carbide Series® Quiet 400Q Compact Mid-Tower Case
Quiet, Compact, and Beautiful.
We’ve engineered the Carbide Quiet 400Q to pack all the power and expandability you need into a gorgeous, compact steel case design.
Keep even the noisiest system internals running stealth-quiet with silenced sound-damping panels throughout – and cool the most powerful components with Direct Airflow technology.
Easy to build, hard to beat
400Q is easy to build – and with full dust filtration, it’s even easier to keep clean.
You’ll spend less time on setup and maintenance, and more time enjoying your PC.
Silenced panels for quiet operation
Sound damping material placed on the front panel, side panels, and even the removable top panel quiets even the noisiest internal components.
Clean, modern lines with an all steel exterior
Get rid of those plastic cases – the 400Q has full steel front and top panels for extra durability and gorgeous good looks.
Direct Airflow Path
One way to reduce noise is to make sure your fans don’t work harder than they have to.
By removing the drive cages behind the intake fans, we provide a more efficient direct airflow path to your hottest components, the CPU and GPU.
It’s just a smarter design.
Compact design, full size capabilities
Don’t let the compact dimensions of the 400Q fool you.
It can house a full ATX motherboard and multiple GPUs should you feel the need to expand.
Liquid cooling capable
With room for up to a 360mm radiator in front, a 240mm radiator on top, and a 120mm radiator in rear, you can choose to quiet down your GPU and CPU with liquid coolers just about wherever you want to.
Two included AF series fans
Great airflow doesn’t have to be noisy -- the AF120L and AF140L fans can push good amounts of air across your hottest devices without that annoying fan hum, and the direct airflow design of the 400Q provides an excellent path for cold air to get to your hottest parts.
PSU and 3.5” Bay Cover
Clean up the inside of your case by tucking all those cables and less-attractive drives behind two modular, clean, and refined PSU and 3.5” bay covers. Or remove them for assembly – it’s up to you.
Easy to clean
Easily access dust filters on front, top, and bottom mean you’ll never spend more than a minute getting dust out of your system.
