Hi, Emanuel Berg photographed:https://dataswamp.org/~incal/ebchw/fan-top.jpgThe case fans look like they would produce a lot of wind if really running at full speed. Whatever, i'd make a closer photo, unplug them, listen how much noise is missing, and then plug them in again guided by the photo. That perforated metal plate at the bottom looks suspicious. Power supply and hard disk cage, if i remember correctly ? How is the noise if you unplug the power of the whole mainboard ? Have a nice day :) Thomas
Nice case. :-)The purpose of the plate at the bottom is to form a thermally isolated chamber for the the power supply. The unperforated portions of the top surface could be covered with sound absorbing material.
Conspicuously absent are drive cages; but I do see drive case mounting screw holes. If drives are not needed, the mounting surface could be covered with sound absorbing material.
The front cover over the fans will help contain noise; especially if it is lined with sound absorbing material.
The unused expansion slot filler plates could be covered with sound absorbing material.
The underside of the chassis top could be covered with sound absorbing material.
The inside of the chassis covers (left side and right side) could be covered with sound absorbing material.
Sound absorbing material could be placed outside and to the rear of the chassis.
