3.2KW isn't that insane for a server, you can buy high end desktop PSU's of 1.6KW (I'm running a 1200W one) if you are using multiple GPU's, a high end CPU, 32-64GB of memory and loads of storage coupled with overclocking and the substantial cooling required it's not that hard to get to around 1KW power consumption on a high end gaming rig these days.
To me, $129k isn't surprising since it is only going to be bought by researchers with big budgets. Small-timers will still build 3x GTX980 systems for under $5k.
3.2 KILOwatts sounded insane to me, but I suppose you'll have your own server rack to put it in if you can afford to buy one of these.
3.2kw isn't that insane considering what you're getting out of it. A coffee pot is 1kw, a toaster is 1.2kw, an electric broiler is 3.6kw. Running costs would be a very tiny part of any budget. Ends up being $9.216/day assuming peak costs, peak usage, and 24h operation.
Are you sure your numbers are right? What kind of dishwasher do you have? And what kind of oven? For the US, at least, most dishwashers are well under 1600W, and few ovens exceed under 3200W.
"To me, $129k isn't surprising since it is only going to be bought by researchers with big budgets" Yeah, this is essentially "Big chunk of a computational researcher's startup budget" or an infrastructure grant.
