Said By Aron SchatzI have an air compressor (a real one) that I use for blowing stuff out. We also have a shop vac (VERY USEFUL when dusting cases out so the dust gets sucked into the vacuum). The support stuff is important.
Said By areamikeI don't personally recommend an actual Air Compressor unless you are experienced and somewhat careful.
Said By areamikeBe careful with the Air Compressor. Depending on the pressure, you can actually blow a diode or other electronic component clean off your MOBO or Video card.
