Looks like it will be a nice build, only a couple of suggestions:
That power supply I have read some bad reviews on such as here:
http://www.silentpcreview.com/article277-page5.html main problems being it is not ATX 2.0+ compliant and that the fan is very noisy and of low quality. I would suggest a seasonic s12 500W instead
Also the x15 g2 stock case fans are run on a full 12v and can be pretty noisy, I would look at either replacing them with 3 x 80mm silenx fans as or a trimmer/motherboard fan headers connector cables.
Oh and if that mobo has the same northbridge fan as the a8n-e, I would look at getting some kind of passive northbridge cooling like a zalman, as the little fan runs at about 5000RPM and makes a lovely whirring noise.
Oh yeah, and no DVD Decoder software nor DVD Drive?
