Mining with zero electricity cost is a no brainer. However you still need to buy the Bitmain Antminer S19 Pro (110Th). Over time you will need to earn back the invested funds in order to become profitable. We also come to the problem of power consumption. The miner you mentioned consumes 3250W!!! You need to make sure that the outlets will be able to provide this much power without blowing out the fuses. In addition to that, drawing 3250W every single second will 100% raise an alarm in the university or at the place you stay at.
It would be better to mine a coin that is somehow ASIC resistant. This means you wouldn’t need to spend a lot of electricity that would cause an alarm. Sometimes people debate if ASIC resistance is even possible, as someone could always make a faster device no matter what.
If you do not own the building and the electricity I wouldn’t advise you to do this. It wouldn’t be smart to go ahead and “steal” electricity (They will see it like that.). They probably provide it to you for free to make you a productive student. If you did something like this and they found out, I am sure they would take action against you. If you still plan to do something like this, ask for their permission first. You could get in trouble otherwise.
