Helpful purchase advice needed on a PC build project

I'm retiring in a few days and my wife & children are
encouraging me build my dream computer as a retirement gift.

For months now I've read reviews and also been a part of
these news groups (and posted a number of questions that
you've all been very kind to patiently answer). Right now
I'm getting ready to finally order the components to build
the "Dream Machine" and try to get the
most-bang-for-the-buck. Would you mind looking over the
components and let me know if you have any suggestions or
comments on the items? It would be especially helpful to
know if you've had problems with any of these components.
This will be my home computer that's used for work and play.
I use my computer for programming, web application
development, gaming, DVD & music, school homework (I attend
the local college as an applied computer science major). TIA.
