Well, as I'm tweaking my new server I was stuck in a decision to install Site Builders for the clients and I read here about someone asking about Site Builder Software, so I decided to make a list

RV Site Builder (Works best with cPanel)
Parallels Plesk Sitebuilder (Never tried it)
Site Builder CX
Site Reptile
(Not Safe + Not Integrated)

Also if you know anymore, then please reply here or PM, so that I can add it up here.
