you have to answer these questions first:
1. are you familiar with what bitcoin is and have you done your homework
https://bitcoin.org/en/faq https://bitcointalk.org/index.php?topic=1944976.0 2. noise,is it going to be a problem
3. heat dissipation,is it going to be a problem
4. power,do you have enough power to operate the miners
5. do you have a legit source of getting the miners from? expect a couple of month's delay between ordering and getting them,unless you buy them from a third party seller
if you are fine with all of the above,you have cheap enough power to be able to achieve fast ROI
