I do notice a suprisingly substantial difference with tasks like iTunes
encoding and Photoshop, and the OS X interface feels a bit more fluid at
1280x1024 - it has to be said on the two minis I played with the switch
to a 7200RPM drive alone seemed like as much of a speed boost as
overclocking to 1.58GHz alone in general usage, though a fast HD helps
more with application launch times than anything else. You could do both
like I did and have a remarkably speedy mini - of course, overclocking
is free (if you don't mind loosing your warranty) unlike 2.5" Hitachi
server drives.
Here's the original article in English
http://www.lbodnar.dsl.pipex.com/macmini/
If your have a 1.42 or 1.5GHz mini, you might to be able to get to
1.67GHz as explained in this article (in French but the pictures
describe the process fine)
http://www.macbidouille.com/news/2005-05-11/#10973
I tried for 1.67GHz, but 1.58 was the highest my 1.25 was completely
stable at in Altivec intensive tasks. You can paint the zero ohm
resistors in using rear window defogger repair paint (from an auto
supplier) or PCB repair paint (from an electronics supplier - same
stuff, double the cost!) after desoldering the existing ones if you're
unsure about soldering the existing ones back on - if you do that, use a
toothpick t opaint it on. It's much more accurate than the brushes or
pen tips these paints come with. Doing it like this rather than moving
the original resistors also makes changing speeds much easier. I
replaced the thermal compond pad (baaad) under the CPU heatsink with
Arctic Silver 5 while I was at it, which may or may not help with
stability at above-rated speeds.
I've had mine @ 1.58GHz for 4-5 months now, and it hasn't shown any
signs of instability or any noticeable extra fan noise (though I did
test very thoroughly with loops of XBench an an overnight Pi calculation
loop at the time I did the overclocking)

Mine runs very cool, even overclocked to 1.58GHz (it's originally a
1.25), in fact the only time I ever heard the fans spin up to full speed
was when I ran the hardware test disk for fun... It's virtually silent
normally, and it takes about 10-15 minutes of 100% CPU load to even make
the CPU fan audible at my typical distance from the machine (It's on my
desk about a foot and a half from me). I hear the HD seeking a lot more,
but the Hitachi 7K60 is a much noiser drive than the 4200/5400rpm drives
they ship with.
