Phenom is old sir.
And Intel is hot and power hungry compared to AMD? You're nutz.
They dont make 7600RPM hard drives.
PSU, any old junk will work? Hrm, disagree.
I know you are trying to help but much of your post is inaccurate.
Yeah, this. In fact, if you're building a new PC, get an SSD. Prices have dropped significantly and they're quite affordable, even in a budget build.
And do spend the extra on a quality PSU. The one thing besides static electricity which is guaran-fucking-teed to fry your expensive components is a dodgy PSU which goes bad. I've always used Corsair, they've done me well.
Skimp on the motherboard, optical drive and grab yourself a cheap and cheerful processor. Invest in GPU and PSU and an SSD if you can afford it.
