If you combine vbulletin with the free add-on vbadvanced.com
you have a simple cms-system.

If you furthermore buy the GARS (Geek Article and Review System) from
www.thevbgeek.com you suddenly have a powerful cms-system.
With GARS you turn every forum into a very advanced article system that
has a lot more options than a lot of dedicated cms-systems.

After some reading and playing with the stuff, you can achieve this for example
http://pdaphonehome.com/
The frontpage is vbadvanced, showing articles made by GARS
(see here how it is done:

But
1) Start learning vbulletin (1 day)
2) Start learning vbadvanced (1 day)
3) Buy GARS and play around with the modules (1-2 days)
4) play around with the GARS-vbadvanced module from GARS and you are flying (?-? days) depending on how much you want to achieve
