With the exception of your PSU, eveything looks ok. Why the Shaw? As a brand, it seems like a fairly low quality brand. Sure, sounds like you get a lot for the money, but they don't seem have a good track record (in terms of reliability).
If it were me, I would buy a quality PSU like a Seasonic. With PSUs, you get what you pay for.
That being said, what is your budget and where do you prefer to buy parts from?
