Cpanel does not comes with memory, nor does DA. However CPanel require around 256MB of RAM, less if it's VPS Optimized version.
With all due respects sady92, what do you mean by, "not like a bunch of kids in DA"
I've been using DA for 3 years now, and never faced any problems. DA community proved to be very useful when I wanted some help, regarding setting up auto backups and installing SSL cert.
I am also using Cpanel, which is also good, but started to have issues with it after upgrading to Firefox 4 / Internet Explorer 9.
Thank you.
