First post on AfterDawn! Anyway, I'm getting overwhelmed by all new things I learned today about building A PC from scratch and I need expert advice. I've been checking deals on newegg and managed to form what I think is a decent computer for gaming and watching HD videos. Here they are: Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case, comes with Three Fans-1x Front Blue LED 120mm Fan, 1x Top 140mm ...

Do you think there would be any problem with this combination of parts? What else do I need? Cables?(i got optical drive, keyboard and mouse already) Any other suggestions? Any help is appreciated. Thanks.
