This is a nice list! I think a Power Supply Calculator might be helpful as well in the buy section.
As for physically maintaining a PC, keeping it clean of dust/hair/crud is important for maintaining airflow, and really all you need for that is a can of air and a shop-vac (Or if you're paranoid, an anti-static vacuum).
When it comes to maintaining the OS, that's a bit more in depth, but just basic things, like keeping your OS patched, along with any third party software. (I'm looking at you Java and Flash) Keeping your drivers up to date.
This might also be the place to add in a suggestion to use Ninite to grab software when the build is complete.

Great suggestions.
