The Sorcerer
oh wow...Xenforo!!!
If you're this sure, Seasonic S12II 430/ Antec VP450.And I think after 1-2 years, it will be quite slow so I will go for better processor + motherboard. That's it. I don't want any separate graphics etc.
You can add GX450 in the list, but I believe GX450 II is available now, to which I am not sure about the power supply with this rev. Make a decision accordingly.
