I did an extensive amount of research today on generic PSU's, monitors, disc drives, etc. and have updated my list again. This is going to be my build for a high-end PC gaming/ academic PC that I'm going to build for the first time. I want to know if these parts will work together with good compatibility, and will perform well. Please give me your input and tell me if I should go with this or not.

I'm also wondering about cooling fans, should I buy one and what should I look for. Or are they even necessary since the Antec case has 3 120 mm fans. Thanks for your help.
