bill, If you're of a mind to mess about inside the box, it is often possible to lubricate or replace the power supply fans.
Although the supplys have warnings about not going inside, as long as you make sure the power cord is disconnected there is nothing to worry about. Once the main box is opened up, you can often remove the supply from the rear panel with a few screws. Whether or not you choose to take the supply entirely out, or work on it in the main box is determined by how much room you have. The supply boxes usually also open pretty obviously and the fans may be also held in with screws through the rear of the supply case. Some fans are connected with three wires, some with two, and some are soldered, some on a connector. You'll need sighted help to find an exact replacement I suggest places like Digikey or JDR micro devices. Or just replace the entire power supply. If you get at the fan, you can try a few drops of machine or three in 1 oil on the shaft bearing where it goes into the fan motor. I've seen all these tricks make a huge difference in noise. Also see if there are any other fans in the case, sometimes in back below the supply, sometimes in front. with the case open, but everything else hooked up as usual, you can turn it on and probably hear which fan is the noisiest. Be carefull how you approach running fans, even the little fans that cool the CPU can give you a nasty cut if you get bonked by a blade. As Dale says unless you can stop the noise by holding onto parts of the case, I think it likely you're dealing with noise generated by one of the fans directly. Just some approaches to take.
