The 500R is among the best cases I have ever built with .... at any price..... At $70 it's the proverbial "brainer". The pics on newegg don't do it justice....on the table or workbench, it's absolutely gorgeous. I love it more each time I use it in a build and I was happy using it when I was paying $130.
I generally use the 500R in systems from $1250 - $2000. The $2000 and up builds now have the new Phanteks Enthoo penciled in.
Everything else looks good tho I can't get behind the Asrock MoBo.....http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.1392846
MSI Z87-G45 w/ 4670k would be a nice step up.....just $8 more.
Id also switch the EVGA SC GFX (1072 MHz) cards (I dont like the idea of reference PCBs and VRMs on factory overclocked cards) for the faster (1085 Mhz) and more robustly built MSI N760 versionhttp://www.newegg.com/Product/Product.aspx?Item=N82E16814127745
