FWIW - Maplin's sound dampening kit (A48AK) works quite well, though not
exactly cheap at 18ukp, especially against HD chassis-borne noise.

Thanks, I'll take a look at it.

But I must say that I'm now into the 2nd day of *relative quiet* ! As
described earlier, this significant change has come about simply by
not using the 'locking lever' on the back corner of the PC case. In
fact, I have to conclude that I must have had it in that unlocked
state before installing my new HD.

I can still hear *some* LF noise, but only downstairs in the lounge,
not sitting here at the PC!
