Re: New build
save your money bro.
If you really want to put that much money into this, scratch the lanbox and get an intel i7 965(thats the extreme), and get the GTX 295. Also get a cpu cooler. The coolermaster v8 looks BEAST. Also if you want you can buy the corsair tx850, i know its 100 more watts than the corsair u listed but its only like $20 more, if you want.
the extremes are very highly overclockable man and are extremely nice, thats why they call them extreme lol.
