You can probably come close to styling an existing CMS, if you want to do it yourself. Most of the CMS's are big bulky animals so many web designers just create their own pages instead. A full CMS allows others to include content in their own sections. I noticed that their comments were powered by "Diqus", this is the clue (I think) that they just wrote their own pages.
You have to decide if you really need a full blown CMS.
Another vote for vbadavnce....all but the forum, arcade, & activity(demon) stream tabs are vbadvance on my forum. And it's free with a multitude of options/ custom modules. It uses your forum default for styling....comes with premade modules..news module being one of them.
