I've been building my own since around 2010. I buy components mainly from Amazon and Newegg, but I also purchase from Fry's and Best Buy occasionally if they have something I need in stock and I can price-match online retailers. I also highly recommend Micro Center. I loved that store but occasionally the location near me (Santa Clara, CA) closed not too long ago and was replaced by a Wal-Mart. The Dell and Lenovo Outlet in the US also have some great deals on refurbished laptops if you are interested.
