I had friends who used to run hydroponics rigs in their apartments (for veggies!), it made sense because their landlord footed the bill.
The only electricity cheaper than hydro, is electricity where someone else pays the bill.
If most of that ends up as heat in his apartment, that could reduce his need for other heating which could offset some of the electricity cost, especially if that other heating is electric heating.
"On November 30, 2017, in response to the complaint agents from the Enforcement Bureau’s New York Office confirmed by direction finding techniques that radio emissions in the 700 MHz band were emanating from your residence in Brooklyn, New York. When the interfering device was turned off the interference ceased. You identified the device as an Antminer s5 Bitcoin Miner. The device was generating spurious emissions on frequencies assigned to T-Mobile’s broadband network and causing harmful interference."
They only narrowed it down to his residence, then he himself said it's the miner. It's totally possible he used it as a scapegoat for something else he was running.
Nowadays, it's mostly impossible to operate the short wave bands in a city due to all the static on the air. The regulation agencies have pretty much given up, save for the most egregious cases, due to how prolific the problem is.
It's pretty sad.
But no. The noise is omnipresent, and there's no way to escape it. https://apps.fcc.gov/edocs_public/attachmatch/DA-16-676A1_Rc...
Surrounding the device with metal containing 2.1cm (0.85in) holes would probably work and only require minor modifications to support heat dissipation.
Side note, now everyone knows Victor Rosario in Brooklyn probably has a bunch of cryptocurrency...

You dissipate the heat into the faraday cage. There's been a patent for this: https://patents.google.com/patent/US5901040
However, I think the fact that the Faraday cage is not symmetric when it comes to static electric fields is very interesting. Ask yourself this: how does the cage know what "inside" versus "outside" means? You know the old joke where a mathematician has to enclose the greatest area with a given fence and so she takes the fence and wraps it around herself and declares "I am outside the fence." Well, why can't I declare myself to be inside the Faraday cage and suddenly get the benefits of its shielding?
You might say that the difference is that the outside has the "boundary" of the universe and that makes it distinct from the inside. [1] But we don't yet know that the universe isn't finite and wrapped up on itself spatially, so if that were the difference, then isn't a Faraday cage experimental evidence in favor of the universe not being finite? I think therein lies the answer: if we wanted to actually use this as an experiment, we would have to place a charge outside of the Faraday cage and wait for sufficiently long time that the electric field is effectively static. However, for our experiment to work, we would have to wait so long that the electric field becomes static on the scale of the entire universe. And so no, the Faraday cage is not an experiment we can practically perform to measure the shape of the universe and the difference is the obvious one: the exterior is the larger one and is simply just "big enough" that we can't ever wait for the EM fields to settle down in the exterior like we can on the interior.
[1] Mathematically, this come in as the fact that the Poincare lemma https://en.wikipedia.org/wiki/Closed_and_exact_differential_... requires a "contractible" domain. The exterior of the cage is not contractible, so we are not guaranteed to be able to use the integral forms of Maxwell's equations over the exterior of the cage. However, the interior is contractible.
“Faraday cages are also used to enclose devices that produce RFI, such as radio transmitters, to prevent their radio waves from interfering with other nearby equipment.”
If I was a miner, I'd be quite worried that someone with direction finding equipment could easily discover a hidden mining location. The FCC or another government entity finding you is kind of the best case scenario if you think about it... :)
A fleet of Antminers, perhaps, but even that would be unlikely.
Edit (addendum):
Details about the stock unit’s noise output; Antminer S5 runs at 61 to 65 dB at 4 feet. Modified S5 with a higher-quality fan dropped the measured sound intensity to 48 dB[0].
Follow-up Edit:
I just noticed that I’d clipped a section of my response...which would have made it clear that my doubt was that the S5 put out emissions that interfered with T-Mobile. I referenced sound later, but only intended that to be a point of reference.
Whoops!
