Is there someone willing to design something like it or any idea which style they used?

The forum is set inside the main website, which looks custom made, you won't get a website like that just by adding a style ;)

Looks like the e-commerce site is the main site and the forum, just add an add on.

Why don't you email the admin and ask who did his site ??
