I am getting a new dedicated server with CentOS 6 and have the option of getting Plesk 11.x for free.
I know, sysadmins are supposed to hate panels, but it would make the client's life much easier (and fewer support requests for me) if Plesk were installed.
I have no previous experience with Plesk and would like to know if like cPanel, Plesk compiles its own versions of software too. If it does then it would be a no-no in my book, as it would complicate things a bit too much for me. Having to deal with custom versions of software as opposed to standard ones would just tip the balance against Plesk.
