Best Way to "Reset" my Pi? So I recently got a Pi and the SD card had Noobs on it and all. Is there a way to get back into the Noobs install to wipe everything I have done put and refresh it?  

I set up a basic web server as a little bit of practice but I already have a dedicated server machine running a private web server and don't really need the Pi server.  I wanted to start a new project but want to free up the space and resources the webserver is using.
