Pre-sales question: What could I customize with DirectAdmin?

[lifehome]

I am going to get Directadmin, but before that, I would want to see if Directadmin fits my needs.

What I need is a Percona MySQL server 5.6 + nginx 1.7.11 + php-fpm from webtatic, on CentOS 7.
While I was reading DirectAdmin's documents, I found out that it automatically installs the LAMP stack...

Is there any chance I could go around this, and specify where the mysql installed, nginx, php-fpm, etc.?
For Directadmin, I only want it exists as the Web server control panel for clients, not automated installation, nor a dummy package...

Hello,

By default MariaDB is installed on CentOS 7.

Directadmin uses custombuild script (please read this FAQ: http://forum.directadmin.com/showthread.php?t=44743 ) to install and upgrade software, while it is possible to have NGINX+PHP-FPM it does not use webtatic to install it, all software (except MySQL, MariaDB) is installed from sources. So you may add, change any option to build PHP, NGINX, etc to fit your needs.
