Any suggestions for hardware to support a full node?

[asdfghj]

Hello All,

I want to set up a computer of some sort that is secondary to my desktop computer whose sole purpose will be to host my miners.

I currently use a raspberrypi and minepeon but my pi is not forwarding transactions, can only pool mine, and effectively cannot vote on the network rules.

Any suggestions on the minimum specs and power draw I can achieve while still running a full node?   A point to another thread would be great too.

Thanks
