When my son needed a new PC, he went to an online PC building company, tweaked a few of their offerings, was given warnings and advice about certain selections, and finally had the spec he wanted.

He then tried to source the same components online, and was unable to get anywhere near as low as the final price offered by the PC builder.

So either the component vendors have huge mark-ups, or the builder has very narrow profit margins.
