The computer I use to run my router cost me $40.
I was a computer that my company was getting rid of, because they upgraded all the old computers.
ABSOLUTELY NOTHING fancy about it. It's just some old xp desktop computer. I think it had 2 gig ram, but I am sure the machine will run on a computer with 1 gig or even 512 ram.
The computer to run a CNC machine is a very small problem.
