so i decided to build my first computer and now im stopped. i realized i have no idea what im doing. i have an antec 900 case and my motherboard is the biostar tpower i45 and i wanted to know where do all the case fans plug into. they arent the usual tiny plugs like the fans on my other computer but a larger 4 pin one. i thought this was going to be easy but i have epically failed!!!!
