Having acquired a typical MDD, I decided to try and quiet the thing. I replaced all of the fans with quieter ones, but still could not take the noise. After unplugging the fans one by one, I found the 2 fans on the power supply were making most of the noise. I looked at an atx solution, but these do not fit without some modification to the mounting. My solution, I bought a micro atx and mounted it in the original power supply enclosure. It was not very difficult, and dropped the noise significantly. It is much quieter. Has anyone else done this?
