believe me thats a good thing -- its not dealamerica's fault -- DVD playback is a CPU intensive task (cpu intensive => heat => your mobo is doing its job in protecting the cpu)you can't leave it on for a long time because it will keep shutting down when playing a dvd movie.
If you're paying less than 799 for a computer from a store you better be careful!we have already taking it back twice, my mom will have to get her money back. i think she will go to wal-mart instead!
So? Nothing wrong with thatthey use a micro ATX motherboard on ATX mid-tower pc case!!
