Guessing this is a gaming rig?
You'v made good choices on the most part, only really brand swapping and small changes.
Here's what I would do.
Change that HIS graphics card to a brand like Sapphire or Gigabyte. While HIS aren't a bad manufacturer, Sapphire and Gigabyte are better.
Sapphire HD7850 OC. $210http://www.newegg.com/Product/Product.aspx?Item=N82E16814102984
Gigabyte HD7850. $210 ($20 rebate)http://www.newegg.com/Product/Product.aspx?Item=N82E16814125419
You picked the slightly older Barracuda drive, there is a newer one on the market with 64MB of Cache.http://us.ncix.com/products/?sku=65701&promoid=1296
Is also cheaper as well.
If you have the cash to do so, I advise upgrading that PSU. 430W is cutting it a bit fine if you wanted to upgrade later. Also this is made by Seasonic (XFX supplies are re-branded Seasonics), so its of great quality.
XFX 550W, 80+ Bronze. $70 ($10 rebate)http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013&Tpk=XFX%20550W
Other than that, all is good.
