Usually I have to tell the newbies to get more fans for case ventilation. But with you, I might have to say you're on the verge of getting carried away unless you are planning on really extreme overclocking. The more fans you have, the noisier the system. Your power supply is adequate under normal circumstances, but with all those fans and drives, you might consider stepping up to a higher watt Antec True Power PS. What you have planned looks great. I'm glad to see a person that has obviously put a lot of thought into their component selection and done some research. I might have to disagree with Sirtoby about the 2.4C overclocking better than the 2..8C. If he means more bang for the buck, then yes... but on "average" the 2.8C will get a "slightly" higher CPU clock speed. Yoiur mileage may vary of course. However, the lower multiplier CPUs like the 2.4C will give you a higher FSB which will boost performance. So, the 2.4C or 2.6C are cheaper, will overclock very nicely, and will give you high FSB. What more do you want?
