Do you open the power supply and clean the dust there?

Would the warranty be broken by doing so?

For power supplies, where one of the screws on the top lid is covered
with a "warranty void if removed" sticker, yes, the warranty would be
voided.

You can blow a lot of the dust out of the supply, from the exterior,
through the vents.

The local megastore sells regular size cans of 3M compressed air
for less than five dollars US, in the office supply area.

No, I just put the end of the vacuum up against the air inlet and outlet
vents. I don't think its worth removing it and opening it up. I suppose if
it were clogged with dust and I could see a problem in the making then I
might, but I've yet to feel the need.

I suppose so, but (i.) most of my equipment is older than a year so is
probably out of warantee and (ii.) to date the only times I've removed the
case off a power supply has been when its blown.
