[quote=djpinc19]I'd suggest avoiding HardwareRevolution because all of the lists are outdated and there are biases causing a number of recommendations to be overpriced or of poor quality.[/quote] I noticed when I was getting those links that the lists haven't been updated in a few months. Maybe he's had problems "irl".
The articles about first-time builds are still useful though.

[quote=tonton346]can anyone reference me to a site that can help me to build my own computer, with a sort of newbies guide?[/quote]
Newegg.com also has a forum that has a lot of info available to help choose the right components and then do the actual build.
In particular, they have a 3 part video series that steps you through the process: http://www.eggxpert.com/forums/thread/727951.aspx

This site also has a lot of good information, this is their "First PC build" page: http://www.eggxpert.com/forums/thread/727951.aspx

You can choose the budget level you have to work with and they'll show you the "best bang for the buck". They don't sell anything, just list the best prices for the best components.

Newegg is the best website for building computers. That's where you'll grab all your parts.
