I wouldn't get a DVD-ROM, get a DVD-RW.
Also, that power supply is of poor quality. You don't need that much power for this build.

Yeah I figured the the power supply was poor in quality after reading the reviews. Do you have any suggestions on a good one? And do I need to buy any other cables or is everything included?
