Hey look, someone who takes a moment to think thoughtfully before posting! Thanks Whyfly.
Now, let's all
just take a moment, take a deep breath, and simmer down.
In regards to the build, I would snag that hard drive today! You can get it for $70 which is a great deal for a 1TB with 32MB of Cache. Some Sammy HDDs aren't the greatest, but I've got the F1 and it has been fine for me.
That ASUS board is wonderful. I recently used in a client's build. I love it. The color scheme, features, all that jazz. ASUS is one of the best MB manufacturers out there. Right alongside Gigabyte. My top 2.
I'm not hot on your power supply/case combo. Yes, you save $20 by selecting that, but for the price of that PSU, you could probably get a modular one. It is high quality, but, why not get a little more for your money! I'll try to look later (I'm currently doing homework...finals week for me).
I'm not up on current graphics cards so I won't comment on that, but I can say that the PII 955 will be a screamer.
EDIT: Just a quick browse through; this caught my eye.
(if you don't mind rebates).
