Overall, Running a System of PC without the case is very useless and dangerous... I got a friend who also did like this, what happened was Suddenly the system cudnt boot at all due to something and once a time His finger got hurt by the Cpu fan.... I dont mean to stress up anything here, But I jus wanna share my friend's experience to y'all and Pls dnt get offended by my statements or everything, Iam just a newbie who wants to get involved in to the discussions and Also I wanna try to be active in this forum since I ve found this very interesting to see.
