That looks like a nice lean mean machine. Although I would like to address the little elephant in your "risk factors" section. The whole "going to shady sites business's" while using the same system to bank online or shop. I wouldn't trust my security to cover this entirely, matter of fact I would advise using your old system for shady website viewing separately from the system your doing your banking with. Of course there is the gaming factor too, I'm sure you are aware of the risks there "personally I would buy a console". Eliminating your unnecessary risk factors will make securing yourself much easier.
