It's not much different than your Joomla! system, that you use at Realm667, really. With some very notable exceptions, however:
phpBB is a forum system, not a CMS system. In fact, any page content you have tied to the forums has to be programmed by hand, or installed from a mod.
Also, blocks are not customizable. You have to make them yourself.
Overall, phpBB is far better as a forum system than Joomla!, however Joomla! is far better than phpBB at presenting content.
If you were to give this site a make-over, though, it could easily be done because of the way the CMS's were made. All you really need is some phpBB templates and some headers/footers/post templates for the CMS's, and you can completely redesign the entire site with that.
phpBB has two sample styles in its download, under the "styles" directory. If you're good with HTML, these styles are easier than you might think to change.
Attached is the c-include.php from the SVN site, which so far is the cleanest coded style file. It contains all the templates used on that site, and similar files are used for the hostees and the home page.
I have a newer version that uses XHTML, but it's not finished yet.
If you really really want it, I'll zip up the NewDRD style for you from the board.

EDIT: Slightly offtopic...
The forums should be faster now.
For some reason, when I imported the database from my computer, it automatically chose InnoDB to store all its tables. If you don't know what that means, it means this: double the disk space, double the access time.
So I've went through and converted every table to MyISAM. This has also increased the site's survivability in its current state, because once the SQL database hits 100 MB, it will stop accepting new entries.
So now, instead of a 76mb database, and looking to move the site to a new host, we're now down to 41mb, and things should be MUCH faster. ^^
