silentpcreview.com is the best place for anti-jet engine information
They provide VERY in-depth information about noise levels, and have VERY good, inexpencive ideas on how to make your computer shut up
they have how-to gudies on things like suspending a hdd by elastic, so it doesnt vibrate the case. And they have lists of the quiet fans for different needed CFM and sizes.
I'm not affiliated with them at all, I'm not even a member, but they have helped me alot, so they are deffinately worth checking out
and btw, check to see if your computer's noise is coming from the vga cooler, psu, or wherever else
a good, high performing vga cooler is the Zalman vf900 (its vsomething, pretty sure "f")
and a good quiet psu is the s12 line by seasonic. newegg carries them. all the models have the same noise levels, with the exception of the 500 and 600 watt models. the 500 and 600 watt models both have the same noise levels however
Not trying to hyjack a thread or anything, I've just been doing alot of research on this and thought I could save you some time
and about wireing a switch. its REALLY not hard at all. you just ....
cut the power switch wire in half
remove some of the plastic insulator stuff so you have a little bit of wire exposed
tie them back together the way they usesd to be, however this time wrap the wire from the switch in with them
put some electrical tape around the exposed wire, so all you see is plastic and wire
and now you have a fully working, two switch system
good luck, and as always when you play around inside your case, make sure you always have a hand on your (plugged in) psu, or guy a anti-static wristguard from your local rat shack for a few bucks, and clip it to the psu.
Also remember to turn the PSU off, not just the computer. there is an on/off switch on the outside of it.
