Replacing old system - Would like review

Replacing old 2.66ghz P4 that I use for basic tasks and DVD encoding. I am doing this in two phases. I am looking to see if the components will match and are good.

Phase 1 - Replace system and use exising CRT monitor
Phase 2 - New video and monitor. Add hard drive, memory and possibly optical drive.

Thansk ahead for your replies.

This is a bit confusing. Are you saying you are going to use your present video card for now?

You list the P5K board and then say it's because you need analog video support... That board has no onboard video.

I doubt you would ever need a 750W, given your PC usage. This is an excellent Pc P&C at a good price:

That would probably last you for many years.
