Is this a good build for my first gaming pc?

I changed the:
-Case Why: A personal thing. The Corsair 300r is cheaper and is from a reliable brand and has more features. I just noticed that the 500R WHITE seems to be 5 more on PCPARTPICKER
-RAM Why: 1333 is to slow. 1600 is good 1866 IS OP for normal tasks and gaming.
-PSU Why: That as terry said, is a tier 4 PSU using Newegg's list here:http://eggxpert.com/eggxpert/computer_hardware/f/135081/t/45344.aspx
Total is 1100

I added a 1 TB HDD from Western Digital because you will want the OS and critical files on the SSD, and the bulk of everything on the 1 TB. You can take it out and get the total back to 1100.

The new total is 1157.15, 2 dollars more.

The 500r is the same price with the newegg deal 20 off promo card and an added sale. Here is the PC PARTPICKER link and the Newegg Link. I like the 500r a LOT.

There are many good 650 watt PSU's for the same price. This is a Tier 2 PSU. Great, but not THE best, which would be more for a smaller wattagage. With this, you have room to upgrade. Plus, it is GOLD certified, which is really good for this price range. Most PSU's would be bronze. This is a great deal, as it is usually 100.

Actually there is a Mail in Rebate to get it to this price. Also, It is semi modular, which makes wiring easier and look cleaner.
