High power vacuum cleaner might as well be a tesla Generator for the amount of static that is generates.
I'd stick with the canned air.

If there's a triboelectric process taking place when using compressed (or uncompressed) air, it's due to the kinetic energy of the dust or other schmutz as it gets bumped about, and that's a function of velocity. Hence, there's no problem using a vacuum cleaner to suck airborne particles away from recently fluffed motherboard. You can even use the vacuum cleaner in reverse to blow the crud off, as long as you're careful about using a decent filter in the air stream.

Yes, I know it says vacuum, but it's not a vacuum. It is a tiny air compressor. Think canned air on steroids.

I've heard that unpowered spinning fans create a generator effect with the fan motor and can cause harm to the system. I had a cheapo PSU die on me back in college when I liked to watch the fans spin real fast with the can of air pointed at them. Not sure if the spinning fans were the culprit for the failure, but thats what I'm crediting it to.

But once the air stream hits the things you're trying to dust off, it'll be full of dust again! Or is the primary concern with elecrical charges that get picked up by the dust on its way up the vacuum hose, and not electrical charges the dust from inside the computer picks up as it swirls around?
Regardless, I imagine that if static charges from swirling dust was *that* much of a concern, using the standard "Dust Off" cans of compressed gas would be problematic as well. (Obviously they're not, since almost everybody uses 'em...)

I expected to find the compressed air nozzles to be the worst offenders, but the cello tape dispensers were the champs. Up to 15kV from those, depending on the width of the tape and how hard one pulled.

Non-permanent adhesives are really weird, when you think about it; residue-less ones like on sticky notes even more so. Scientists have been trying to figure out, and duplicate, things like gecko feet for a long time; there are some wild atomic-level phenomena involved.

I recall reading an article a couple of years ago about some scientists who discovered that unrolling Scotch tape in a vacuum generates nanosecond-scale bursts of X-rays, so there must be some unbelievably intense electric fields being generated (albeit over a microscopically short distance) as the adhesive peels free!
