this bad? i ask this because i saw an "open case status" in the bios and i got concerned. why is there an option for it? i only have an nvidia 6200 with a fan so i dont think thats whats making it hot, plus the computer itself has 2 fans. its not overclocked either. but nevermind all that im only asking this - is leaving a case open while the computer is on bad for it in any way?
