While there is no need to inundate beginners with technical details, there is a good cause for at least listing some citations for the claims this article is making, as well as resources for further exploration and learning. There are many build guides out there, but perhaps a beginner wouldn't know what words to use to search for them, so here are a few:
To a beginner, the power supply section seems to suggest that the actual units differentiate based on whether they contain bronze, silver, gold, or platinum, when those are just the names given to the different levels of energy efficiency certification.
In addition, it would be worth noting that a large downside to playing on a PC has just been removed because the Xbox One and PS4 will both, for the first time, be using the same computer architecture as PCs, which at least means that PC ports will be of a higher quality and might even mean that more games get ported!
Why give a beginner a guide and tell them to drop over $700?
There are plenty of builds for $500 and under. You don't need to drop $100 on a power supply, especially not for a $100 graphics card. You don't want a $100 graphics card. You don't want a $200 graphics card with a $300 processor. There are plenty of coolers from $20 to $30 for builds that anybody can use.
There are a lot of pretty good boards under $150... 99% of modern boards support external graphics and have on-board audio.. plus 2gb of visual memory... really, toms? you're telling newbies to look at video ram size as a basis for buying a video card?
Sorry, I didn't mean to cause controversy. I suppose that science and math have changed, and perhaps there is truly IS more to learn. I have tried to keep up to an extent,

This article is stupid. If I were ignorant to Pc's this would in no way encourage me to give it a try. just by the way you did not include the cost of windows! Most of the other costs listed are too high.
