Not only do these guys have ridiculously good value deals, in their "Today Only" Section, but the interface for the website helps you get the need to know information about the components you're buying.
Once the sale is finished however the service doesn't stop. When I had a power supply that blew up on a computer I had built for someone else on the other side of the country. It was easy to sort out an RMA, and these guys did it super quick too.
I love that they have a facebook page which allows you to interact with them directly too.
