I'm pretty sure that there is no difference in price from ordering all of the components at once or a few at a time. If you enjoy opening packages then order a few at a time so you get more packages.
yes it troubles me to think that such a widely resourceful website (newegg) to get everything you demand for computers does not have good shipping prices...like omega said there is a serious flaw in newegg, its their shipping, they charge you separately for each component that you order, in which case, like omega stated, what would be the point? do it now rather then later so its easier to put it together as soon as u get it
If u get it part by part u have to see it all day and it will only be half done, but if u have enough money i would get it all at once so u can just start building and start playing.
