This is a tricky one. I'm fairly sure this system will never be "silent", but hopefully I can get it below "tornado" levels
The system has a number of restrictions which make quieting it difficult. These are primarily:
The case. It is a mini-atx, "tiny tower" case. It has a 60mm fan opening on the back and space for a 60mm fan behind the front bezel. Airflow in it is atrocious. I am willing to make modifications to the case, but would like to keep it looking as close to stock as possible.

The mobo is an ECD K7SOM+. It has a non-upgradeable, AMD Duron 1300MHZ CPU surface mounted. There is no CPU socket. Fitting a new heatsink will be difficult due to this. It also runs very hot.

The PSU. It is a bog-standard, SFX power supply. It is loud. I'll probably need to do a fan mod on it. I haven't opened up the PSU yet, but I'd imagine I'll need an 80x80x15 mm fan for it.
I have a 60mm Papst fan which is reasonably quiet if I put a fan mate on it and run it at about 1900 - 2200 RPM. The PSU fan clicks all the time, and has loud "wind" noise.
The CPU fan is really loud. Also, the heatsink is alumninum only and quite small.
I need suggestions for mods to improve airflow, a CPU cooler that I might be able to adapt to fit, and what to do about the PSU.
Thanks in advance,
