Overall, that looks like a mighty good build.
IMO, there is a couple things that could do with some changing.
If you can afford it, go with the ASUS A8N-SLI Premium, instead of the plain version. It is $56 more expensive. The reasoning behing this recommendation is that the regular version comes with a very poor quality chipset fan that is notorious for dying. The Premium comes with passive cooling which does a better job at cooling, and doesnt randomly die
If you aren't overclocking, then there isn't any point in getting anything more than ValueRAM. In my system I am using Mushkin Green Series RAM
. It's inexpensive too ($86.99)
Also, I don't know how good MSI PSUs are. Someone else might be able to vouche for them. However, I don't have any experience with them or have heard much about them. So, I'll recommend this one
