Residential Mining In The Future?

So, right now it’s cool that you can GPU mine profitably, primarily due to Eth still being proof-of-work. But, that’s likely to end at some point when they switch to proof-of-stake. So, outside the HNT miner which has enough threads already, are there any other residential miners that are still likely to be good for the future? By residential, anything along the lines of not being super noisy or requiring rewiring your house for 220 Volts? (again, outside the Helium miner :D)
