It is hard to make arrangements to co-locate your mining gear all because they're cutting into your profits which are so tight to begin with. The miners that have their own data center, free electricity and noise is not a factor will be pretty much these last mining rigs coming out can handle. After the middle of this year my guess the "consumer" is pretty much out of the equation due to power requirements, even louder gear and just the size of the hardware. Maybe 1 out of 10 people have their own rack in their basement but that's also in a small community in itself. I'm still trying to figure a way to get an SP30 and not having enough money isn't the problem. Price and logistics have made their way into my life.
Traditional colo is dying out making way for cloud hosting. There are plenty of under-utilized data centers looking to lease their space out. I was able to work out deals where the cost of the rack space AND power is less than the residential rate power I would have paid at home. You just need to know where to look, because these DCs don't usually advertise.
