when I ran the iBuyPower AMD A-Series APU system configurator I came up with $642 for the config you show above. though it advertises starting at $419, but the basic config shows $499 before adding the HD 7750 and the 600W PSU.
I ran a similar system through the CyberpowerPC configurator based on a i3 2120 chip and h61 MB. March madness gets you a free upgrade from a Radeon 7750 to a 7770. overall this is a better budget gamer for the money $554. if you bump the PSU up to 500w or 600w its $22/26 more. I dropped the liquid cooling as you don't need it an i3.
you will be much happier with the performance of an i3 and a HD 7770.
You can't build it via newegg for this pirce and you don't have to worry about DOA's and such.
