Go Western Digital or Samsung instead, avoid Seagate. Pay a little more for the Vertex 3 120gb. This PSU is a better choice. This is a nicer case if you want to spend a little more.

[Blulight]

Get a cpu cooler and overclock that i5. This one is good and only $40. This one will give you better results in a overclock going past 4.5ghz, a little more but worth it.

Save a couple bucks and go with with this mobo.

The Fractal Design case Chaud linked is very popular. I would recommend the HAF 912 at $60, but I don't see it on the website you are using.
