Not a great idea for computers! Canned air is fine. Try not to blow it into the power supply.
I've read of people using the air hose at the local garage, too- which they find out is a hugely bad idea, those things often blow a LOT of oil out along with the air, making a huge mess on your computer innards.
Good advice on compressed air from a shop. What does work very well, with no van de Graff generator issues is use a leaf blower (air broom ) on a low velocity setting. You need to do it outdoors where you wont care about the dust, but the large volume of air will push the dust out of all the nooks and crannies. You hold the air broom off the computer 24" or so, and it only takes a couple of minutes to blow one clean.
I have to compute in a very dusty environment and have used this for a number of years on Macs and peecees.
Compressed air, leaf blower or vacuum all can generate static electricity. The difference is that with a vacuum you have to get the nozzle in close to remove dust which greatly increases the chance of static discharge. So keep your compressed air, canned air or leaf blower back and you'll be okay. I use a compressor or canned air. My compressor is a diaphragm type with no oiler so it isn't a problem for oil.
I will sometimes hold a shopvac nozzle over the computer while blowing with compressed air. This sucks up the loosened dust and keeps the dust from just settling on some other equipment.
