I have no idea where your buying these parts from but your paying way too much for them. This is of course i am right in assuming you live in the U.S and not Canada (which if you are would explain why the prices are so high). Your part list is good so i'm going to redo your list with cheaper updated prices and show you your savings and what to do with that savings.
Get the E6850 instead. You can get it at that same price your paying for the E6750.
Intel E6850 CORE 2 DUO E6750/ 3.0GHz/ 4MB CACHE/ 1333FSB/ LGA775
$285 (Note: Go to ZipZoomFly.com to get it at this price)
