That i7 860 build seems a bit wonky. Go with an i5 750 instead, you won't notice a difference and a cheaper board like the one on
PCPers mid range build page Add a 5850 to the i5, dump the dedicated audio card you have no need for it and with the price difference grab the pieces that aren't included in the build. I believe the TR build was also using a 140$ case or something ridiculous like that, A 60$ Antec 300 will do the exact same thing for you. and the Corsair 650W will be plenty for you no need to use the 750W unit that PCPer has up.
It could be prudent to wait a week or two for these sites to update their building guides as the market has changed quite a bit since the Fermi cards were released.
My reply is pretty distracted and i'm rambling but you also won't need a network card, your motherboard will cover all that just fine on its own. Maybe i'll get started on a quickie build for you. You'd rather have quality components in your machine than the bottom of the barrel components you'll find in pre built machines.

The motherboard should be swapped out for one like on the PCPer build that has USB 3.0 (Might have had SATA 6Gbps) but you're looking at 100$ less for a machine that will serve you much better, and a way better mouse too. You won't have to ever buy another case, power supply again (until something breaks heh), kb/m etc, and your memory will likely last you your next build as well. You'll be able to overclock to performance levels far higher than the i7 860 and building a PC is as easy as building with lego.
RMAs can be an annoyance though, but you can always buy your components from a local brick and mortar store and simply return/exchange if there are any problems.[/QUOTE]
This build is great and all, but it's missing a DVD drive and an HDD which if included would put it at pretty much the same cost as the pre-built he went for.
