For PSU, I would get this http://www.newegg.com/Product/Product.aspx?Item=N82E168... and it's much better and has 7 year warranty and it's only $3 more. The PSU is actually built by Super Flower which is really good.
Also I would avoid buying ATX motherboards. Most of the time is unnecessary and it's just waste of space. I had a Coolermaster HAF 932 and I've downsized to Silverstone SG09 and I'm really happy with the airflow and temperatures. So my advice is to try to buy a MATX motheboard which will give the possibility to move later on to a smaller case.
Also you should buy a SSD for your OS.
