Hello there,
At the moment, my budget is around 1500$. I am interested in multiboxing 10 or more clients, I don't care about settings (can go down with rendering) and if its needed I can go without any addons. There is no need to have "power" available for other things such as twitch, etc.
I'm also not planning on going into a content such as raids, just a basic farming of herbs or 2x4 farms, atleast for now.

What would be the absolute minimal requirement to hold such a multibox farm? And if I get some cash in the future, what would be the minimal optimal one?
Thank you for your help!
