I'm not familiar with Intel components, but I'd be iffy about any motherboard that included onboard video these days. The motherboard is the one place I don't spare expense; a good motherboard will let you upgrade at will and provide much more stable performance in my experience.

You could opt for a lower wattage power supply if you want, unless you're planning on running two video cards. I probably wouldn't bother with a sound card as most onboard sound chips these days are good enough for what most people need; other than that I don't know anything about Trust sound cards, if I had to get one I would go with a Creative card. I had a bad experience with a Seagate drive so I keep away from them, but that's my personal bias. If you're going to go with a 7200 RPM hard drive you might consider cutting a corner somewhere else to get more space on it, as 80 GB will run out very fast these days.

My two cents, I'm not a technical master, so I'm sure someone else will have some more insight.
