I'm intrigued and hesitant at the same time because I know nothing about building a server. I've only built gaming rigs.

*Pending everything is doable and available while still remaining relatively cheap, I'd be down for 1 board and 4 procs and ram.

I still have questions:

Approximate Cost to make this happen?

How to house the board?

Vid card needed?

OS needed?

PSU needed?

Could you please make a walk through showing exactly how to setup everything once you get your test unit up and running?
