I have been looking for some kind of electric air duster for the PC but all of the small 'computer' ones are priced £45 upwards, however I have found many leaf blowers priced as little as £16+, my question is would one of these be OK to use on PC or would it be overkill and maybe damage the parts? and would it be able to get the harder to reach dust out or should I try and find something with a smaller nozzle option?
