The board supports raid 0, 1, 5, 10. Here's the user's manual http://dlcdnet.asus.com/pub/ASUS/mb/...74_P8Z77-V.pdf
Ive only used "raid 0" years ago so ive no idea how to set it up. It shouldn't be to hard if you read the manual. And you can always google a bit if your still clueless.
The monitor comes with all the cables you need. DVI-D, HDMI, DISPLAYPORT, VGA. I suggested you to buy a calibration tool becouse you said you are a web designer. So accurate collors is very importend but i doubt its your profession otherwise you would have known about this.
And why did you create another thread? This question could have been added in your older thread. Anyway bob dont worry its gonna be all right
