All of those components are bottom of the line or outdated, yet the total price you've quoted is still quite high, I would keep shopping around if that's a package deal, or start again from scratch if you've selected the components individually. Try searching on YA! for system ideas, there are loads of system configs on here, all of them better than this one, and cheaper too.
