Case designed for low noise usually include quiet fans, and often come with a quiet power supply. Some incorporate heatsinks to cool components passively.<ref>{{cite web | url = http://www.silentpcreview.com/article301-page1.html|title=Fanless Ultra Powerhouse PC by EndPCNoise | first = Michael ‘Mike’ | last = Chin |publisher=SPCR |date=2006-02-23| access-date=2008-10-10}}</ref>

Larger cases provide more space for airflow, larger coolers and heat sinks, and sound-dampening material.

Case designed to be quiet typically have wire grills or honeycombed fan grills. Both are far superior to the older style of stamped grill.

Features that facilitate neat cable management, such as brackets and space to run cables behind the motherboard tray, help increase cooling efficiency.

Air filters can help to prevent dust from coating heat sinks and surfaces, which dust impedes heat transfer, making fans spin faster. However, the filter itself can increase noise if it restricts airflow too much or is not kept clean, requiring a larger or faster fan to handle the pressure drop behind the filter.

====Soundproofing====
The inside of a case can be lined with [[Soundproofing|dampening materials]] to reduce noise by:
* attenuating the vibration of the case panels via extensional damping or constrained-layer damping
* reducing the amplitude of the vibration of the case panels by increasing their mass
* absorbing airborne noise, such as with foam
