Or then there are the two prebuilts I am considering...

What do you guys think would be the best for a system that will probably be going for the next 5 years. My old parts I am keeping date back to 2005. If I go with the new build, is my power going to be enough? I'm not sure how to know for sure.

Please add or take from if you have better ideas.

Thanks for the help.

Build your own. You've already got most of the parts and your replacement parts tally only comes out to 210.97.

Your 400W PSU will comfortably power those components.

Since you're not doing any heavy duty gaming or graphics, you don't need any more than you've picked out.
