Looks fine other than a couple of issues.
The 450w PSU is cutting it way to close and the Corsair CSM series are low quality at best. Look at something like this:

Secondly, make sure you need 32gb of RAM, RAM is not as cheap as it was a few years ago. If you do, I'd advice you swap that Corsair Dominator stuff out for something cheaper like this:
http://au.pcpartpicker.com/part/gskill-memory-f312800cl10q32gbxl. Corsair Dominator RAM is really overpriced, you are paying for the looks and that's about it. The performance benefit is minimal to non-existent.
Also consider whether you really need the 980, you are ordering a 1080p monitor which is relatively low resolution, a 970 would be more than sufficient. Failing this, consider a higher resolution monitor, something like 1440p. 1080p on 27" is pretty horrible, 1440p will at least take advantage of the larger screen by giving you a lot of space to work.
Your network card is fine although running a dedicated wire to the router will always be better than a wireless connection so do this if it is at all possible.
