I'll 2nd (or 3rd) newegg, the reviews by users are often helpful too. I would say if you are a student and thus have a free year of Amazon Prime it might be cheaper once shipping is added. Free 2 day shipping is a real steal if you have a .edu email address.

What are you planning on using the PC to do mostly?

Since this is my first build, I'm going to keep it simple and probably just make a general purpose computer.  I will probably use it for school work mostly.
