Recommended Server Requirements

[RsultsMayVary]

I bought a quad-core gaming laptop with 6 gig of ram etc. etc, to run a server on AC because I could not find anything anywhere recommending a type of machine to use for it and I didn't want to use a service to host such as rackservice.

I think it might have been overkill, but does anyone know the minimum requirements for a computer to run a server on?

Also how much bandwidth is needed, both upstream and down?
