May i know what MB , proc , PSU you used ? <| sep |> You think it ' s okay to curbstomp somebody for trying to break into your car ? <| sep |> LSU saying they are just rumors . <| sep |> definition of cringe <| sep |> Doing an air purge would be one way to go , but to do that ' properly ' I would want to use a case that I could close off all air passages except a single vent to the outdoors so as to not leak a bunch of CO 2 into a poorly ventilated space that may have people in it . The sort of systems that you are describing have to be VERY careful to not go off while people are in the area , due to suffocation and such . I would encourage you to think long and hard about safety if you are going to do this . All that said , I ' m convinced most cases would contain any fire you could certainly find a robust unit that should do the trick . If I were being super paranoid I would install more protective devices like fuses and MOVs to limit possible failure conditions .
