Its not as risky as some people say, obviously dont talk about it is the #1 rule. But regarding the smell i know tons of people who smoke trees in their living rooms in apartments and have grow ops that never get busted. Its kind of hard to get a warrant when a hallway smells like pot when it could be any number of houses or reasons. Be smart about it but the pc grow case is a dumb idea. plants grow much taller then the height of a computer case, i mean come on havent you ever looked at a plant on the internet or some shit? Even in the vegetative state they get pretty tall, how the fuck would a pc grow box work? And if your actually going to do this you need an hid light, end of story. Fluorescent lights produce shitty yields and shitty bud. Your going to need to do a little more research before growing, your not growing something simple that you put by the window water once a day and poof pounds of weed.
