I have a compressor and that's what I normally use. but I would like to leave the computer on the desk and not have to pick it up, take it out side and spray it off, then back in. Is there a vack with enough pressure to work as good and not have a static charge. Also arnt you forcing dust in corners where it will get stuck. Kinda like the old game cartridge

Vacuum will simply not work, the effect will be far too weak in pretty much all household vacuums to get dust out of places inside computer.

And no, there is no real danger of dust getting stuck in corners. for one, most compressed air cans (and air compressors) beat mouth based blowing at least 100 to 1 as far as pressure and amount of air is considered. The dust will fly off. Also the stuck in corners dust needs something extra besides dust to actually stick, like.. in old cartridges.. moisture from your saliva.

The reasoning why it works better outwards is that the pressure pushes air outwards too, kind of like nuclear bomb cloud. Where on vacuum side, most of the air is sucked in from closer to the pipe and it's sides.

Nope. Compressor + outside is the best way to do it and you are not forcind dust into anything you can't force it out of using the compressor.
Depending on the environment you only should have to do this onece a year or so, so what's the problem?

By this nature, push does better than pull.

The static carge problem exists pretty much because the pipe is made out of plastic, if it was metal, there would be no static build-up but... metal is also conductive. Of course if you are paranoid, you could always anti-static wrist strap the metal pipe. :p

You could kind of do both though if you want to avoid some of the dust spread, keep vacuum nearby, use compressed air and.. vacuum if positioned right, should be able to take majority of it out of air.
