Nah, OpenBSD with a good desktop environment is perfectly fine for someone who doesn't want to use the terminal. I don't think
mattthumper is saying no terminal, ever. I think he's just saying minimal terminal usage, if I really need it to set something up, fine.
With that said: I honestly thing you'd be best served by running one of the large desktop environments on your machine. OpenBSD has all three: Gnome3, KDE4, and Xfce4.
Unfortunately, though, there is no GUI package manager, so you will need the terminal to install/uninstall packages.
Code:
# pkg_add gnome
# pkg_add kde4
# pkg_add xfce
Choose any one. All three have graphical volume control.
