Thanks for that, I am looking at msi k8n neo4 and the 939 option would as you say give me a better upgradeabiltiy. Savastore has all I need although I am looking at the links above. I have not sorted out a power supply yet and I will probably asking some questions very soon. I have noted the suggestions and that should keep me busy for a day or 2.
I was going to look a the mb manafacturers site for graphics card options.

Any prefrences with DVD writer or are they all resonable ?
