I never understood people that try to shove a GPU into a work PC because of 'free power'. So, let's lose a job that makes more in an hour than we'd make in two weeks of mining. At some point someone is going to hear the GPU running, notice the power spike or the web traffic going to a mining pool. Try to explain to your boss and HR what 'this bitcoin thing is', and see what they look like when you start talking crypto currency.
