Here are the current system builds as of 4/7/2014. This is the most economical system.
It is a basic system that will perform most task, play DVDs, some video games. This system is the most cost effective system with enough performance to keep most people satisfied.  This is not the cheapest system that can be made but, an economical system to get the job done. There are 3 systems you can choose from but, you may ask, "Which one is right for me?", I like to use the car example, "They will all get you from point A to B but, how fast do you want to go?"  Do you want a basic or level 1, basic gaming or level 2, Great gaming or level 3 or a No holes barred or level 5. Finally a cheap quite system for HTPC. Need to build a complete system with keyboard, mouse and monitor, then check out my system extras page.
