Thanks everyone for the help.
still it doesn't clearly identify the reasons on why one mining rig can't be done in a home.
comfortably? - either a small room, one rig with 8 GPU is not that big, unless you are using a server type PSU and have a hell lot of noise
My friend and I purchased 12 miners and we ended up not having enough space to run them at home.
There are many hidden costs to keeping the miners inactive.
https://miningsky.com/2018/03/24/miner-hosting/Miningsky's article mentions sunk costs and maintenance cost for inactive miners.
Hosting services should be a major concern for individuals such as you and your friend as the cost of hosting varies depending on where the hosting location is.
Crypto-Geek, I just realized I purchased the miners from Miningsky but on Ebay. And it turned out they also offer colocation and hosting services, but I think my quantity is too small. Most of what they are advertising is for much bigger operations...
