Well Mining is normally done by Proof of work, that's why the GPU's and ASICS "mine". When switching to PoS, the miners will loose their work so the coins will literally not me mined anymore by working machines.
Right, I see. I guess what I was asking is if there are coins that make the mining system more helpful for smaller setups, but now that I think about it that question doesn't really make much sense. Thanks for the reply, anyways!
