I'm just building a system for movies and music, I'll probably go DVI-HDMI to my TV and use it as a HTPC but it might take over as my daily use PC, I don't know. It won't be used for gaming. I have 5 400GB Seagate drives (7200, IDE) that I can use but I'm wondering if I should just sell them and go SATA? Will I notice a difference? I don't have a mobo picked out yet, but I'd like to setup some kind of RAID set.
