The Enermax EQUILENCE case is the perfect solution for Silent PCs. Thanks to the high-density sound-absorbing materials in the front, upper and side panels and a 4mm tempered glass panel with insulating frame, EQUILENCE ensures extremely quiet operation. In addition, the case offers excellent cooling performance with 3 pre-installed 120mm fans, the possibility to install up to 6 more and with extensive space for radiators up to 360mm. An integrated fan controller allows you to adjust the speed of six fans on three-speed levels.

EQUILENCE comes in a clean dark design with a glossy finish front panel. A frameless tinted panorama window built from tempered glass offers a wide view on your hardware.

Silent Operation

High-density insulation mats in the front and sidewall, an insulated, removable fan cover and 0.8 mm thick SPCC steel absorb sound and vibrations.
A 4 mm thick tempered glass side window is fitted with a sound-absorbing frame for a tight seal.
The air intake is located on the side of the front panel, which reduces the sound escaping from the front.


EQUILENCE offers an extensive cooling potential for up to 9 fans and several options for liquid cooling radiators.
An integrated 3-speed fan controller connecting up to 6 fans allows the optimization between silence and cooling performance.
The top panel can be removed to accommodate radiator up to 360mm or 3 fans.
An extra 360mm radiator can be fitted in the front of the case.
The great flexibility makes the case perfect for modding with custom loops.

Storage Installation

The PSU tunnel can support two more 2.5″/3.5″ HDD/SSD in a tray at the bottom of the case.

Flexible System Configuration
