I have bought 2 - 200GB Maxtor Ultra DMA Hard Drives which I am going to use for Movie and Music Library. Do I want to get another Hard Drive to use for my Operating System and all other programs? My UDMA ATA 133/100/66 Bus Master IDE connectors are full and I could go witha SATA Hard Drive for this. Is this overkill or my best plan of attack? This will be my 1st PC Building experience so I'm sure I'll be back with tons of questions in the next 2 weeks.
