As this is my first custom build PC, I would like to confirm that these components are from the cheapest sources and are all compatible with each other. I am a PC building noob and I am following a guide (http://www.pcmech.com/byopc/step-1-materials-required/) Is this guide up to date and usable? I play source games and I want to be able to record sometimes and get at least 30 fps on most games, the graphics quality must be around med-high. My components; please tell me if I can get it cheaper somewhere else, and if they aren't compatible what do I need instead? I am building a gaming rig as cheaply as possible without getting 4fps on every game like I do on my 1.8 GHz laptop with 3gb of ram...

Note: I AM A COMPLETE NOOB, I may have made a huge mistake, so don't get angry, and please spare me too much technical language!
