Back in the basement
At the Uni where I used to work, we had a large room in the basement that had been cleared. Not sure what it was used for before the clearing as I didn't have access, or a reason to use it. However, when my boss took it over, he had the idea of bunging a couple of technicians and several high spec computers down there, to build a state of the art computer lab. All very lovely, but with one slight problem (that I did point out to the boss beforehand and was ignored). The area we were in was on the banks of the Thames, and had a bit of a problem with flooding. This wouldn't have been much of a problem if we'd bought Desktop PCs, or even mini-towers. But no, my boss wanted big fuck off towers, so the students could see how much money we were spending on them. I suspect, if it had been an option at the time, he'd have gone for the full gaming towers with LEDs everywhere. We even bought the lab it's own domain controller. Again, in a very wide server style towercase (this thing was the height of a full tower, and about 19inches wide), which sat on the floor in the technician's office.
So, a few months later, it rained. Heavily. Thankfully the lab was closed, but when the technicians got in the next morning, all the PCs and the DC were waterlogged, and obviously, dead. With the entire team, it took a couple of days to dry everything out, clean it (had to clean all sorts of shit from the cases and motherboards, and repair any problems. We had the lab up and running after a couple of days (and a lot of disruption), When we did get everything working, we made sure to put all the computers on the benches, not under them, My boss was furious. His mood not really helped by a technician jokingly suggesting we should buy a speedboat to navigate this lab.
Thankfully, in the long term, the problem was solved because the Uni moved out of that building, and put that lab on the first floor of the building it moved to.
