I'm a long way from being a computer expert, too, but I did have time to go through it. But if you don't have time, you don't have time.
Openbox is great, but if you have to set it up, it requires learning some things. Well worth the little bit of time it takes to learn to use it, in my opinion.
There is no Linux Mint Openbox Community Edition, of course.
I think there are a few Openbox-based distros out there, like CrunchBang Linux. Maybe that is what you're looking for.http://distrowatch.com/table.php?distri ... crunchbang
