does anyone have experience with building their own desktop. Newegg offers 1000's of options already bundled and compatible at pretty good discounts. seems much less daunting than picking out the parts on your own, especially the power supply which i know is a big deal. I love the idea of it being easier to upgrade. i get free copies of office and windows through work so i can save there as well. any experiences, thoughts, or advice would be appreciated. I have a few snow days to kill so this has become my latest obsession.
