Water and electricity mix very well, unlike in the saying :-)
I've got an ice bath I get in while it's running, with a power strip next to it I could splash. I don't care. I've had several 240V shocks in my life, chances are it doesn't kill you.

That looks like a lot of unnecessary neatness. I have a large bookshelf in the garage I stick anything on and wire it up in a very ugly fashion. Two of the motherboards aren't even in cases. The electrons don't know what it looks like on the outside.

I am beginning to think if I have one monster system to tinker with I may be a happier camper.
Personally, I prefer several systems as it gives me more options, ie crunching several different kinds of tasks at the same time or maxing things out and putting everything on one kind of task.
In your case with the 3080Ti's, you could get a smaller CPU-based pc just to run them and then a monster CPU in the 2nd case with a less than 3080Ti in it to play with.
That sounds like a great start for another thread. Let me see now...
I collect what I'm given / find cheap. Anything is possible with the right adapters.

I am looking at selling some of the hardware to help fund an upgrade to a "Monster" level server (24c/48t) that might be driving the 3 Rtx 3080's, and maybe the gtx 1080 and Gtx 1660 Super all in one box (err... mining frame).
If you're still selling, let me know what you have. Although I'm in the UK if that's a problem for postage. Even broken stuff that could be repaired. I have some GPUs that gamers sold me for virtually nothing because the display output is corrupted.

Power: 208v outlet for increased efficiency and expandability
Why 208V?
We only have 120v lines here at the school (well, in my building). Getting a new 240v line run would have cost an absolute fortune since we would have had to go through a commercial vendor (no choice). Instead, we were allowed to modify the existing lines to make the 208v line. This was done to allow expansion and power efficiency. I could add another GPU to the workstation OR additional workstations to this line without cause for concern. Right now, under full load, our main workstation pulls about 1200-1300 watts continually, which is about 50% of the possible output from the line.

I don't understand. American houses (I assume that's where you are) have -120v 0V +120V. Anyone in an American house can use 120V or 240V.

How did you increase 120V to 208V? A transformer? And why that weird number? Why not 240V?

Not sure why you have so little electricity there, unless it's somewhere in the remotest parts of Africa, but in the UK every single outlet provides 3250W. There are lots of these in each room of a house or school or any other building.

Correct- high school building in the US. Every outlet is 120v, 20a. I WISH in the US we used higher voltage, but... 120v is the standard. I know I could run 2,400w through the standard outlets, but I wanted plenty of overhead because I want to further expand what we offer our students. Also, the PSU in the Dell Precisions is a little picky about what it can supply to the workstation, depending on the incoming voltage.
I cannot claim to know what exactly the electricians did, but they were able to complete it without having to bring in a contractor. And, they were excited about the overall project so they were happy to complete it.
Your distribution panel for the school uses 3 phase "Y" configuration where the voltage phase to phase is 208V and the voltage phase to neutral is 120V. So all your electricians did is connect both Line legs up to two different phases.
Same trick as connecting household distribution up to L1-L2 to get 240V.
