Make these extra features a choice at install. Just like the "Add\Remove Features" control panel. A short check list where you can add things from catagories like: HTPC, Languages, Input, Networking, Admin tools, Games.

OEM PCs could come with a package tailored to the device intent and the user could later add and remove these packages.

The PC, being a personal computer, should be personalized by definition.
