phpBB forums

How hard is it to set one of these up? Do you need a computer set aside to run solely as a server? As you can probably tell im not very intellectually gifted when it comes to these, so. im interested in getting a too human forum set up. If even just for my sweet eyes . Toohuman.net is a giant clusterfuck with everything you could think of everywhere - with alot of stupid ideas in their thread make up.

So yea, how hard is phpBB to set up?
