Yeah, openbox is great. Use it on my desktops for 2 years now after switching to *BSD. Openbox
theming isn't that hard. The only thing that disturbs me a little bit is that you have to use .xbm button images.
This is my actual dualHead home desktop with a self made OB Vertex theme to match GTK
Vertex theme of horst3180 and a Numix Square icon theme

Other software is
deskutils/cairo-dock,
deskutils/pypanel (top bar on the left screen) and
sysutils/conky (top bar on the right).
My OB Vertex theme isn't completed yet but I could share it if you like. And here is a shot of openbox as I used it some time ago on my T420s with an AwOken icon theme and
x11/wbar.

As
Phishfry mentioned take a look at
vermaden's nice
Blog for almost everything around Openbox customization.
And look at the Screenshot
Thread 8877 to see what awesome desktops some guys run on FreeBSD.
