Try these cheap mods first:
Open up your modstream and switch the fan for a Nexus, Yate Loon, Papst or other quiet fan. Cooler Master fans are very quiet and also cheap. This is much cheaper than buying a Seasonic and will give very similar results.
Try suspending your hard drive with elastic (visit
www.silentpcreview.com or
www.7volts.com).
Run your existing case fans at 7v or 5v. See above-mentioned websites for guides. Install Speedfan and slow down your CPU fan.
Get a Zalman cooler for your graphics card if it becomes the loudest part of your system after this.
Try lining your case with sound-deadening material. The denser, the better. Thick vinyl floor tiles are good. Dense acoustic foam works too, as does industrial carpet, and so on. You could experiment with a cheap Wal-Mart foam mattress pad.
These relatively simple and cheap mods will give you a much quieter system, without going to the expense of a new, expensive 600W PSU, three expensive Nexus fans (and they are expensive as fans go), and an expensive SI-120 heatsink. After doing these mods, re-evaluate whether or not you need it to be any quieter, and then you can go from there.
