    My pentium II rig (see sig) is currently being used as a backup machine running 2k server, which for it's ages, it manages admirably. Tiny flaw in the system, the PSU sounds like a jumbo jet turbine....i want quiet, but because of the age of the old dog, i don't want to spend much money making this thing a little quiet....even if it is reliable.

    Any ideas? The CPU fan, is virtually silent, so i don't think i'm going to even attempt work on that

    Well if your just saying the PSu is loud then replace the fan in that. MY guess is if it's a regular At PSU then it will just have an 80mm fan on it that you can cut the leads to and replace fairly simply. Pop it open and look. If you want really quiet then cap the wires to the fan then take a wire from one of the 12v lines on your Psu and then one of the 5 volt line and use those. That will make the fan run at 7 volts so it will be something like half as quiet(or atleast some what quieter).

    sound might also be coming from your HD's depending on there age (you know how the older things get the more they creek at night (haha). You could do the rumberband trick to silence them (google).

    With all that in mind just listen to it and find where the noise is coming from and stop it so to speak. The 2 things i told you are fairly cheap i mean at most $20 that is at most going with like a panflo fan or something.

    Just be careful inside your PSU. There are capacitors in there that store a hefty charge even after disconnected from the power.

    If you're going to do a fan swap make sure you discharge the psu for at least 24 hours (to be on the safe side).

    Some people unplug from the mains and then switch the psu on and off several times whilst still connected to the motherboard etc. Not sure how reliable this method is.

    I tend to bend a paperclip and connect any black pin with the green one in the main atx connector, then switch the psu on. Obviously this is when the psu is disconnected from the mains and the motherboard etc.

    If it's a decent psu then they may have a fan connector inside, otherwise as infered101 you will have to cut wires and solder.
