I lived in a house with 2 other guys, and due to a lack of cash, and work, (winters are dead in RI) i built us a caseless computer once, it sat on the corner of the kitchen table!!. after about 4 months it was caked in dust, smoke, ashes, beer, and whatever else 3 drunks could spill, or drop on to it. Never had a problem, all of those components still work!!
Oh, except for turning it on, you had to use a screwdriver, or knife to short out the power header on the Mobo!! Ouch
