ask specific questions or to present your build from pcpartpicker. TONS of resources here. I would suggest doing a simple Google search for your research. As for ordering your parts, go to newegg.com, NCIX, or Microcenter. I used Newegg, and it’s the most popular, but using various sites you can take advantages of sales and minimize your price.

Making Space
Get your place ready for the new guy coming in. If you have an all carpet place, and your buddy is going on the floor, buy a wooden board he can sit on so there’s airflow. Don’t buy one if there isn’t any perforation on the bottom of your case. My case has that, thus really good air flow (it’s known for it).
