I'm surprised I wasn't able to find any discussion about this.  Maybe my searching skills are soft at the moment. 

Is there any easy way to combine the appliances together?  The real benefit of turnkey appliances is the out of the box configuration is already done.  But since I'm running a home server on old hardware, I'd like to use it for multiple purposes without needing to go through hours of configuratino to get all the pieces I want.

I have gone down the route of a full ubuntu server install and then piece-meal installs of the different servers I want.  I find this route interesting as I like learning the details, but often times it actually hinders me from getting my real goal accomplished.

This is just an off the cuff idea, but is there any turnkey base install that provides a menu of all the pieces you want?  This would be very much like the ubuntu server install, but when you select the different appliances, it would use the default configuration that makes turnkey so valuable.
