Bill, the main thing I notice about your list is that you're not mentioning brand names much, which can be very important if you want a quiet machine. You make no mention of which power supply you have sitting in the case. Cheaper supplies that come with cases are usually louder than the more expensive models and this is usually the single biggest noise pollutant in a system.
Have a search around on the web for the Nexus NX-3000 300watt model. I've got one and it's quieter tha the two QuietPC PSUs I have in my other machines. These in themselves are very, very quiet indeed but the Nexus really surprised me. Great unit. There are passively-cooled PSUs out there which use huge heatsinks on the back of the unit, but they don't seem to be particularly easy to get hold of and are
expensive.
Also - what hard drive have you got? If you want it quiet then a Seagate Barracuda IV or V is a must (the newly released 7200.7 series are a tad louder by all accounts). There are no quieter drives - end of story.
CPU fan - liquid cooling is expensive and tends to be used by those using higher spec chips and/or overclocking - don't bother until you've got the rest of the system as quiet as you can get it. Take a look at the Zalman Flower Cooler (copper version). It's a big-ish heatsink with a weird 'flower' fin design that dissipates heat very well. Supplied with it is a 92mm ultra-quiet fan which bolts to the inside of the case and is
silent when your case is closed. It's very easy to fit and cheaper than some of the more exotic coolers out there and is good for all Athlon XPs up to the 2600+. I have one running in my second machine on top the same Athlon you have (same motherboard too). It would probably be my first choice if I needed another.
The graphics card - does it have an onboard fan? There are replacement passive coolers available which will cut out another source of noise.
Cases fans - there's quiet fans and there's
quiet fans. I use Papst models in mine which cost a silly amount of money but they're pretty good. There's a lot of choice though - too much perhaps, so keep an eye on the specified db level. If it's 25db or over, it aint quiet, believe me. 10db-20db is more like it.
A word of warning though, even to get your PC down to
quiet levels (as opposed to extemely quiet or even silent) will cost money. The components aren't cheap and manufacturers have learnt they can make a whole load of money from this new area of the market.
There's a great site which reviews and talks about all this kind of stuff:

Also, have a look at
www.quietpc.com They sell all sorts of low-noise PC components.
