I would put two of them in a computer case and use it as a nice desktop setup then let it fold for the good of humanity when its sitting idle.
I am pretty sure miners are the last people to ever do Folding@home. They are generally only in it for the profits. I think the people that do Folding are mostly students who just use the Universities electricity.
From what I understand you earn points and can redeem those points but its not for anything valuable. So I am pretty sure the OP will just leave his rig unpluged or throw it on eBay/Craigslist.
