Removing the ability to buy!

Hey guys, I'm new here and I have similar problem as captaincrunnk (http://forum.opencart.com/viewtopic.php?f=5&t=2704)
I have OpenCart V1.0 ... and I found the difference between the locations of folders and files !

I'd like to know how I would go about removing the actual um..commerce aspects of OpenCart. I would like to use it for an online catalog but I don't want people to be able to actually buy the items from us or add them to their cart, etc.

Thanks for any help!
