I'm using my SATA hard drive from my current computer (300GB)
Using my current Cd/Dvd w/ Burner disk drive

The question I have is should I use my current power supply or get a better one?
I am using an Antec 500W atx power supply. Since I am going to be having a lot better processor and I am changing my video card how should I upgrade it, if I have to. Thanks for the answers.

Get this mobo instead:

Cheaper and better.

The stock fan for the i7 is fine depending on how much you want to overclock. 3.2ghz is fine with the stock fan. I use the v8 coolermaster with mine, I don't think it is the best though, someone will recommend a better one.
I use the Antec Nine Hundred two case, but I don't really recommend it. Its a bit small, wire management sucks and there are no mobo speakers.
As far as the power supply is concerned 500W is probably cutting it a bit fine. I think it is worth investing in a 750W corsair PSU, so your set for SLI or adding HDDs in the future.
