I had a preorder in for this but I canceled a few weeks back.

My experience trying to run machines this powerful in residential settings has been extremely poor.

All of the Seasonic power supplies that go beyond 1kW or so will trip my shitty (i.e. probably defective) Siemens AFCI breakers. Not even the same circuit all the time.

Even after violating local electrical code, I have found that living with a 1500w+ monster inside my house during the summer at 100% utilization is a complete joke. Unless you live in the perfect datacenter climate (i.e. the people who designed the tiny box), this thing needs to be inside. All of that wattage is pure heat being dumped into your home. The HVAC solutions in most residences were not designed for this kind of heat load. It would be like running your oven with the door hanging open all day. For those of us in places like Texas, this machine simply would not be feasible to run for half the year.

I don’t know much about US electrical standards but aren’t your residential circuits rated for 1800w or 2400w? Here in New Zealand they are 2400w and people regularly plug in 2400w fan heaters without issue.

Yes it wouldn’t be pleasant running this 24/7 in summer in any living space. But you could install a heatpump with 7kw of cooling capacity which should handle it (adding to the electricity bill).

The residential AFCI issue I describe isn't about the wattage directly. It's about transient currents generated by large switch-mode power supplies being detected as arc faults. Similar concern as with induction motors.

That is interesting. In New Zealand AFCI is only required on 20A sub circuits in places that have a high fire risk, contain irreplaceable items, school sleeping areas and some other minor circumstances.
In the US the National Electric Code caps draw at 80% of rated load. So a 15A circuit is permitted a 1440W load even though it should handle 1800W.
Crazy. Our hair-dryer has 2kW.

In my experience, the Siemens AFCI just do that. I recommend switching them out for Eaton AFCI. That fixed all my nuisance tripping, especially from induction in other lines

I didn't realize Eaton had AFCI breakers listed for use with Siemens panels (or that they work better). I swapped it out for a non-AFCI Siemens, but if I can make it code compliant I'd much rather that.
Yeah. I think they have seperate models, I forget the details but it's working in my panel!
If you're spending $15k on a box, you can also spend $1200 for a small insulated shed kit and $800 for a small mini-split heat pump. I live in a much warmer summer climate than Texas and this solution works fine for me for my small network cabinet.
If the main argument for the box is compute/$, "and then you need to spend another 20% on top to even make it work" is not the most winningest position. (20% because you also need to pay an electrician for the two-circuit wiring. Well, three, you want to run the heat pump too)

At that point it isn't super price-efficient, it's an absolute space hog, and you need to maintain a whole bunch of infra. Still might work for you, but it's losing a lot of general appeal

Could you not duct the heat through a hose and out a window? Like with portable AC units
yep, or drop it in your basement. also, will help heat your home during winter.
