... Are you saying the ambient air temp will not be cool enough?
Finally.
Locale dependent.
Now go read my first post.
I mean is that your question?
There are fluids that boil at 76 celsius and you only need ~15 degree temperature difference. Does it get to 60 degrees celsius in Israel?
As for resale, it will still be possible. Shipping blades will be cheap and there is a conversion to air cooling.
Untrue. To take advantage of IC DT, you need to design your boards specifically for that purpose. You can't use them outside.
Here is the AC conversion I am talking about (looks a bit like an sp10):

Although I don't know who you would be selling hardware to. Maybe someone who pays $0.01/kwh?
You'll always find someone to sell it to. It depends on the timing and cost. Maximizing ROI is done by selecting the best timing. With IC DT you can't do that. You throw away old HW.
But when you throw out the hardware you don't waste a case, heatsinks, fans, powersupplies, etc. Only boards which can be replaced a several times faster than an air cooled DC.
