I modified a ATX power supply for my laptop. My laptop required a 12V 5A
P.S. when everything (floppy, cdrom, sound to the max...)was on. Since
this requirement was very low compared to what it could give i installed
a dummy load (Power resistor) just to keep the switching circuit happy
with a load when the laptop wasnt hooked on. I also reduced
significantly the noise level by hooking up the internal fan (12V) onto
the 5V output. Everything is working great for several months now

WRONG (grin). My original question was, essentially:
Has anyone stripped out the original power supply of old "junker"
PCs to realise the same noise and power saving of specialised 
thin-client hardware?? 

Other postings so far have suggested measuring the current draw of
existing power supplies in PCs using an inductive clamp meter.  This
something I have and I can do that sometime soon.  

I guess I was asking the group what they thought of my intended
and to find out if someone had already been down the same path.  If
that's not the case then I will embark on my adventure soon and then
report back my results.  Unfortunately, I don't have any LCD monitors,
but the power savings of these over CRT monitors is pretty
