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 (http://www.rvsitebuilder.com/) (Works best with cPanel)
Parallels Plesk Sitebuilder (http://www.parallels.com/products/plesk/sitebuilder/) (Never tried it)
SiteGalore (http://sitegalore.com/)
Site Builder CX (http://sitebuildercx.com/)
Site Reptile (http://www.sitereptile.com/)
SiteZEN (http://www.sitezen.com/)
SohoLaunch (http://www.soholaunch.com/) (Not Safe + Not Integrated)

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