Building a new PC and need some opinions.

I'm building a new PC and need some opinions.

Processor:http://www.newegg.com/Product/Product.aspx?Item=N82E16819103871

MOBO:http://www.newegg.com/Product/Product.aspx?Item=N82E16813186189

Case:http://www.newegg.com/Product/Product.aspx?Item=N82E16811147111

Memory:http://www.newegg.com/Product/Product.aspx?Item=N82E16820134812,http://www.newegg.com/Product/Product.aspx?Item=N82E16820134657

I am upgrading from:http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01070884&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3440626

I also would be transferring a GTX 260 and upgrtaded PSU from the old PC along withany random components I might need from it.

All of these items would work well together, and give me abig boost in performance, correct?

Also a silly question but, the new motherboard has an integrated LAN for me to access the web, correct? lol.

Any opions would be helpful, Thanks!
