So a mother board has a primary and a secondary ide connector. Each of those can connect to two drives. Now, if I want to connect say a DVD-Rom, CD Burner, DVD Burner, and three hard drives do I just get an ATA133 IDE CONTROLLER RAID CARD?
The 350W should be fine to support 4HDDs (I ran 4HDDs and 2CD/DVD drives on a 300W before) -- depnding on the graphics card hehe... some of the newer ones require dedicated power too and so you need to take this into account. You can also try using just an IDE controller card (it usually comes free with Maxtor 80GB+ ATA133 drives). If not, just get a raid card -- not onboard RAID, in my (unfortunate) experience, onboard raid is crap (from the ASUS A7V-333)
