simple portable mining rig for working away

Hi All,

I am just getting into mining cryptocurrency. Ethereum seems the way to go at the moment. I work away from home 3 weeks out of the month. I want to make up a rig to run in my hotel room and at home. So I need a transportable GPU rig. I have a spare nVidia card, but I don't think these are as good as AMD. Can anyone point to a good start up guide, so I can give it a go?

Thanks in advance for any advice or ideas
