Are you sure you want that expensive case? There are other cool cases that are cheaper such as the:
CM HAF Xhttp://www.coolermaster.com/product.php?product_id=6653
and the Corsair Obsidian 650Dhttp://www.corsair.com/pc-cases/obsidian-series-pc-case/obsidian-series-650d.html
Everything else looks fine, although you really don't need a 850W PSU, a 750W would be more than enough for SLI in the future.
Finally: You don't need a network card if you're going to use the ethernet cable. If you are going wireless, then you need a wireless adapter, although if you're gaming, I do not recommend wireless
