Also I think that if you don't game at all even a 5450 would sufficient.
If you don't plan to overclock I suggest getting the H67 chipset that way you can make use of the integrated graphics and save some cash there as well as just having a cheaper motherboard as well. Plus you save the money that comes with the "K" annotation.
I think you should get a Asrock Pro3 P67 instead then, it'll save you some money and it's a decent overclocker @ 130$.
Oh and remember. High overclocks are not a guarantee, they are a plus. Any higher than 4.1ghz I'd say is a given.
Case: Fractal R3 115 $ (lowest)
Suggested by forum users because i want a quiet good looking case
That case is designed to try to quiet systems a lot more demanding than yours.
Assuming you select a quiet power supply, your system is already going to be quiet so there more reasonable cases that are designed for quiet operation that will suit your needs fine.
That's an excellent alternative but I have more confidence that the Seasonic will be quiet. The 430D is a Delta unit.... decent but not always quiet, or not always AS quiet as Seasonic.
Then there is the 5 year warranty vs. 3 years.
Unless the budget is very tight I think it's best to stay with Seasonic. I also chose it because the Antec PSU he had listed is made by Seasonic as well.
But I agree the Antec 430D is an nice budget choice.
