I do not have seperate machine room, and my giga computers are very noisy. I\'ve looked into issorax and other soundproof glass cabinets, but they are pricey. I\'m thinking how hard could it be to build one, or convert a regular wood rack cabinet by adding a glass door, insulation and a fan. Does anyone have any experience with this and knowlege they can share. I really don\'t know what kind of fan to put in and how to vent it properly so thinks don\'t overhear - while also keeping quiet.
