I know Newegg usually has everything at about as cheap as can be...but what are the other sites out there that get your business or have a good reputation??
Newegg... oh wait, you said Newegg. Okay, heres one, Newegg.
Hehe, I was burned by a few others several years back trying to build my own and ordering for the parents. I felt that paying an extra $10 for a part on newegg was WELL worth it considering they've never screwed anything up for me.
Resellerratings.com before you buy anything should help too.
Since you have already found NewEgg, you really dont need my opinion since I was going to suggest it.
However TigerDirect.com seems match everything NewEgg sells.
Just based on their quick shipping and support, I'd still go with the Egg.
