Best way to clean out your PC of dust build up?

+1 for the DataVac

They really are awesome. I never looked back to my compressor the second I used my data vac.

I use an air compressor, invest in a moisture trap.

I personally use an air compressor. It is by far the best option, albeit not the cheapest.

Because the brush bristles are made of nylon that can damage your hardware from esd. Not to mention if you aren't careful, you can pop capacitors or resistors off with a brush.

If you leave the pc plugged in but with the switch on the wall or on the psu in the pc set to the off position you won't get esd. You will be connected to earth via the plug in the wall but will have no power flowing through anything as it's in the off position.
