Erm, I did went and have a quick glance through InsanelyMac.
Also, I don't know the precise specification about my board.
The graphics though is the Raden HD 3200. This 3200 series and 3300 series are only for integrated ones.
To reply your question though, my DVD-ROM is running on SATA.
My board is actually quite an old one if you ask me, or maybe I'm just a greedy guy. Haha.
Nearly forgotten to ask the Sapphire Ultimate HD 3870. Will it run using the OS X?
Because I already got the card which is on the way.

By the way, thanks for your quick reply!
And the time now here at my place is the time to sleep... then need to go school.
Leave your questions and answers here. Desperately wanting to use this.
