I was reading this thread in its entirety and here are my comments:
- I use an Antec TruePower 430 PSU and it has no whining at all, despite having two fans; it does make some noise but, to my taste, very tolerable, because I am still looking for a fan that makes no noise; it's just impossible because noise is air in movement and the function of a fan is to move air, so... I had, prior to this Antec, a SilenX PSU (that had one fan) and it was quieter than the Antec but unfortunately it died after some months of use; I contacted customer support and they were very nice to send me an RMA that I never used (I was living in Brazil by then), so they are not to blame.
- I have an ASUS mobo, P4C800E-dlx that has no whine, no sound at all; I do have some noises coming from the speakers (best noticed when using headphones), when I move the mouse and the volume is high, and I am still to find a solution; this is a driver problem, not a mobo problem, imo. I am using the on-board sound.
- My LCD monitor is a Samsung SyncMaster 213T that has no whine, no sound at all. It is just a wonderful monitor.
- My Linksys WRT54G v3.0 emits no sound at all.
What I do have that whine are three hard disks that I keep in my old computer (on purpose, because they whine badly) and an APC 600BR nobreak, bought in Brazil, that has some humming: it powers my main computer.
My case, an Antec P160, is prone to ressonance: the best way to avoid it is to remove both side panels; for as weird as it may be, my system is quieter with the panels removed. Lately, I have them on, to avoid dust inside the case.
Other noisy equipments are my printer and my scanner
My main system is:
Pentium 4 3.2GHz

Seagate Barracuda IV - 40GB - ATA100
DVD-RW NEC ND-1300A

Second system - in another far away room

SMS Manager III (Brazilian nobreak)
PS - oh, I forgot to say that all four HDs are mounted inside the case with no screws, to avoid humming (it gets a loud humming if I use the draws that came with the case). I just passed some jumping cord through the openings and I sit the HDs on top of them, so they are actually loose (I can't carelessly move the computer) and no humming comes from the four HDs.
