Plenty of people happily would... I personally would do it in return for the electricity cost of the GPU's and machine. That's my marginal price to do so. However, that offer is only valid if a project can guarantee my computer experience won't be degraded. So it needs to reliably run only during idle time, or, if it wants to run while I'm using the machine it can't make any application laggy or throw errors about not having enough GPU RAM. I think there are probably millions of GPU's available out there with similar terms to mine.
