The GPU alone has a TDP of 700W, together with everything else (CPU, RAM, storage, fans) you're looking at 1500W+. Depending on the country, that may be enough to saturate your home's electricity uplink...

That's actually less bad than I assumed. High-end gaming GPUs are already almost at 600W with peak usage above that. I assumed it was much worse than that; that seems absolutely feasible for running at home.
Never heard electrical uplink before but to those wondering Italy, India, and Japan all have requirements around 3kw. I was slightly surprised by this, but in the end if your running this in a tiny space with that low of power your already probably not buying used H100s.
Hell no. 1.5kw is half a socket capacity. A heat pump or many kitchen appliances are using much more. Our car charger uses more as well.
That's why they said "depending on country"
In North America we are on 120V, making a standard 15A outlet only 1500W max, and something like 1200W sustained. To use higher wattage appliances, we have to upgrade our outlets to 20A (2000/1600W) or up our voltage to 240V, but that carries a different set of plugs and outlets as well.
Usually the home service is 200+ amps these days which is 24 KW total across all circuits, though you're right that most individual circuits are only 10-15 amp.

It's 1800W for short periods and 1500W sustained.
In the US they have a 120V system so it might actually saturate a normal socket over there. My PC room has a 16A fuse and 230V though, so should be plenty :)
The US has a 240V system for residential power, not a 120V system.
Most homes in the US have 200 amp service. That's 48 kW of power available to the house, though code states that you can only pull 80% of that continuously, so 160 amp/38.4 kW.
The 120V misconception comes from the fact that it is delivered as split phase on two 120V legs. Any competent electrician can run a 240V, 50-amp (40 amps/9.6 kW continuous) circuit to any room in a house. Plenty of homes have these circuits for electric ranges, EV chargers, or RV power outlets, and there's nothing stopping anyone from having one of these circuits installed in whatever room they'd like it installed in.
Heck, my old landlord and I installed one ourselves to provide an outlet for an EV charger in the garage of a house I lived in about a decade ago.
400 amp and even higher service is available, though it is fairly uncommon. Plenty of large houses will have a 400-amp service, though, which means you can double the power numbers available that I mentioned above.
Most North American homes would have 240v and 200Amp service. A 16Amp fuse seems down right tiny:)
We have 50 amp service running a hot tub and another 50 amp service line to charge an electric car.
A typical hair dryer uses about 1500W. I guess GPUs are mechanically not much different from a hair dryer.
Install it in your bathroom, use it like a restroom hand dryer.

One that runs continuously
