Here is a link to my PSU ducted Sonata.

Components include:
Antec Sonata Case with 120mm case fan connected to "fan only" connector.
Abit NF7-S V2
Zalman NB47J Northbridge cooler
AMD Barton 2500+
Zalman 7000A-Cu Heatsink and fan turned all the way down
Corsair 512MB XMS 3200 Ram
ATI AIW 8500DV video card
WD 250GB 7200 RPM HD (Data disk)
(2) WD 120GB 7200 RPM HD's (OS and Backup OS)
I have cut out the bottom bezel area for improved air intake and added a PSU duct in the top 5.25" drive bay. The PSU duct helped immensly! Right now it is cardboard and duct tape, but I'll be using steel plate and aluminum exhaust tape for the final build. Also will be adding a front washable air filter.
Stock temps:
case: 34C

250GB HD: 38C
120GB HD: 40C
Room temp: 24C
Modded bezel temps:

CPU: 45C
250GB HD: 35C
120GB HD: 39C
Room temp: 24C
Modded bezel, PSU ducted, zalman 7000A-Cu, Zalman NB47J temps:

250GB HD: 30C
120GB HD: 35C
Room temp: 24C
Adding the PSU duct dropped my case temps by 5C! All of the cool air is now going over my components instead of through the PSU. It really helped my HD temps as well. Down 5C as well. The ambient room temp remained the same throughout. Also, the Zalman is completely inaudible, yet still cools almost as well as the stock heatsink which was very loud.
The Zalman 7000A-Cu does fit the Abit NF7-S but the silver mounting bracket touches the nearest capacitor and the outer mounting holes have to be cut off. You *could* reverse the blue and silver mounting brackets, but that would be putting uneven stress on the AMD die and I don't want to chance it. The Zalman is so heavy that I'd be really nervous with uneven pressure and such a massive heatsink.
The Zalman NB47J had to be modified a bit to get it to fit the northbridge, but it was worth it. The stock NB fan is horribly loud. The mod was easy with a set of tin snips and removal of the stock H/S fan was as simple as removing the 2 retainers and lifting up. Abit uses thermal goo, not thermal epoxy so it just comes right off.
I didn't have enough length on my ATA cable to do a great cablegami job, but I did manage to get them out of the way enough to allow airflow.
Now I have to tackle my video card (probably replace with a fanless ATI) and try to suspend my HD's somehow. The Sonata doesn't have much room in the HD bay area and my configuration is desktop style so I can't just rip out the HD bay and elastic suspend them. Working on something though.
Anyhow, feel free to give me your comments.
