I'm looking at making a super cheap rig I can just leave on while it mines. So far, while looking at what I have already, I only need a Mobo and CPU, already having 8GB DDR3 of generic RAM and a 750ti gaming. I saw some good ebay deals and picked out a Dell 200DY Optiplex 780, and an Intel Q8400. I was wondering if all the parts I listed would even be compatible, before I stupidly check out only to find out it was a waste of money.
