Get some plexy glass, and a few corner molding strips that fit it... You can find these at home depot or another supply store. The molding strips are usually white in color, and hold two peaces of flat board at a right anglel.
Take a peace of plexy glass, and cut a circle in it the size of your powersupply fan... then drill some holes in the places where it attaches the power supply to the case. This will be the base.
Now take the molding and build a rectangle box of 4 peaces of plexy glass, leaving the base side and an adjectent side open. Apply a little superglue to the molding, for this will hold it in place while you construct it... After you construct it, the nature of the construction will hold the box together.
Now when your at home depot look at the vinal floor section... They sell a black thin pladding that is made to absorb noise from vinal floor installations. They are really cheap rolls, and are not a thick material... Almost like rubber (which you may also use)... I recommend spray on adhesive for this. (you can also use this stuff in your case, to quiet it down)
Glue on the base of the box to the base of plastic you made with the fan hole. Superglue works well to hold it in place, but some gorilla glue or an epoxy is best. Becarefull Gorilla Glue expands while it drys, and can make a mess.
The open side can be pointing in any direction you want. I like to point it down since my powersupply is about 5 inchs from the ground. Make sure the box is big enough not to restrict air flow... But not too big that it doesnt stop noise. The Box should be tall enough to cover the whole fan.
Now use the screw holes, and as many washers needed(to fill in any gaps in the screw on installation) and some to spread the pressure of the screws accross the plexy glass. You may even glue on some of these washers directly to the plexyglass with some supper glue.
Sand the whole outside down with a 150 sand paper. Spray paint only with a Primer... do not use color spray paint because it will come out like crap... if you want to add color buy a 1/4 gallon, and roll or brush it... Try not to use a pure gloss for it tends to leave an uneven look to it.
This duct should silence most powersupplies with very little air restriction, and should look like it came with the machine. If you have the equipment make it out of steel.
