anything that you guys suggest that will make my first build a successful and positive one will be greatly appreciated.

I am probably going to change my DVD drive to a SATA as i heard that it allows for a cooler computer.

The build looks pretty good. I just have a couple suggestions:

I would get a 22x SATA DVD burner for sure. I don't know why they even still sell IDE drives.
