Asterisk added to hard drive with existing application

I like the convenience of installing asterisk in a flash but, it wippes the hard drive.

Trying to conserve power and want to put a single camera cctv system “running zone minder as we speak” and asterisk with some type of call reminder for appointments on the same dell work station.

I do not want to go though all the headaches of the past, and loading all the asterisk dependencies, drivers and modules. Front in gui install interface is fine.

I run a dell work station and a old x100p card…which I would like to replace but will use in the mean time.

Anyone can provide some recommendations?
