Like i said in the beginning of this project as soon as i had done the model i realiced that a regular psu wouldn't fit because of the case size but abowe all the pyramid shape .So i had to get myself a server psu and after some serious digging i got this one : http://www.zippy.com/P_product_deta...name=1U Single&pcpw_rfnbr=3&pp_code=P1H-6400P i chose zippy because they are known for making very high quality psu,s they also make a hole in your wallet 150 pounds,well well lets start with the installation of the psu. As soon as it arrived i had to test it because i heard that server psus with their small fans often makes an irritating sound: Unfortunately this psu was no exception ,so i started thinking out a way to silent the fans i finally came up with the idea to put 2 sound absorbing walls with a 4 cm gap betwen for the air to run throu its basicly the same thing you can do to a computer http://www.ixajt.com/sarkofagen/sida.jpg , this is a sketchup of it so u might understand better ,(I'm a very poor at sketchup i have only used it 3 times so its ok to laugh ) : The psu silenter contains 3 main peaces and this paper model contains all of them, base ,back and front (i used the front and back piece out of same model with a small change do: Base cuted and bended: I took out a rubber math from a hdd silenter box and cuted out peaces witch i later putted on the sound absorbing walls ,u can also see that i have done 2 alu square bars to hold the psu: Here the is psu mounted on base and space for cord has been done: Here i im working with the 2 aluboxes: And this is wat came out one box for outblowing air. And one box for incoming air: Here is some pictures of al 3 parts and how they suposed to be mounted (upside down) ,u can also see the sound absorbing rubber inside the boxes : And one pic of the gap betwen base wall and box wall: Now its time to install the parts in the case i started out by cuting out a hole fore the outcoming air from psu: Then i instaled the base ,(the power cord will exit in the hole for outcoming air): Here is the front and u can see how its mounted over the opening: And the back part ,u can see that its realy close to the door and back of case: One pic of all parts in case before psu instalation: And here is the final result ,i also put rubber where the cords comes out: How well this sount silenting works remains to be seen until i fire this thing up . but i heard that people who has built computers this way got them really quite. (I think im the first one to do it on a psu do ) Well that's it for today comments are of corse wellcome ,next update will be on next sunday.
