i'm thinking about building a hcpc . i would like it to be able to capture and play back video and 5.1 sound , play dvd and music. i would also like to have a case which looks good and hides away the dvd rom drive. it needs to be networked to my other pc also. the other thing i would like is for it to be as passively cooled as possible. can anyone tell me what components i need to get to achieve this.
