I'm almost done loading up a new Gentoo installation paired with MythTV and a hardware MPEG2 encoder. I'm looking forward to finishing but before I let it loose upon my television, I was wondering what else I should compile in. Samba File sharing? A webserver (for watching shows on the road)? A CPU/Memory monitor? An additional media player? Not to start a flamewar, but should I do KDE, Gnome, Enlightenment, or some other window manager (especially when viewed on a TV screen)? What bells and whistles can I add to make my system that much more complete?
