Ok, lets see.

DataTank = Cheaper. We can build a few for you if you want, and I can almost guarantee you will love them and thank us later Wink

- Price of DataTank =~$0.50/W = $500/kW.
- Ready to mine machine, including power, network, servers, liquid, everything required (brand name parts).
- Just add internet and a power feed from the grid
- Or even easier, let DataTank Mining run it for you and we charge $18/kW per month (+ a modest 20% managing fee)
- Reduces power consumption (lower leak currents, no fans, etc)
- Lower price is the whole point, why would we build it otherwise?

ASIC hardware side:

- ASIC hardware is now reduced to boards and ASIC chips.
- No more power supplies (ie. SP30 = 2x 1200W, $200-$300? so $100 to $150 per kW)
- No more enclosure ($50 less??)
- No more heat sinks + fans $25 less?)
- No more assembly etc (maybe $50 less?)
- No more heavy duty FedEx shipping charge (maybe $150 less? so $75/kW)
- $300 to $350 saved on each SP30 so far (and days or weeks assembly and purchasing time?)

For heat sink mining you still need a building, some CRACs or fans, and of course power:

- $100/kW cheap hosting (or more) = $600/half year
- Or build your own mine = Huh

? few hundred dollars per kW China style to few thousand dollars per kW Washington State style

- 19-Inch racks ($300-$500 in China?)
- Switchgear, power distribution, cables and power strips? (DataTank has fully automated remote PDU)
- How much space for 576 of your SP30? That's what fits in a DataTank.
- 144 racks at 10kW/rack, or 72 racks at 20kW per rack (and 2,500 CFM / 1,180 L/s of air flow per rack)
(20 to 30 racks in shipping container, so a couple of shipping containers on the way from China just for your empty server racks, another $100 to $200 just for shipping)
- Roof, walls, building etc ?
- Fans, fans, fans. More fans. Even in Iceland. And dust.
- And so on.

There is no doubt in my mind. Heatsink miners will soon stay behind. And go deaf too Wink

As usual antirack is omitting the cost of:

- water tower
- water pump
- water circulation pipes
- fans in the water tower

His whole marketing campaign is aimed at illiterate/innumerate people, those who can be convinced that the law of thermodynamics can be somehow suspended after paying for an expensive patented 3M cooling fluid. The reality is obvious: you can't omit the heatsink, but it can be either local or remote.

Interestingly, they actually built some of their water-cooled setups so they must have the exact costs available, they just don't disclose them, hoping to snare some semi-literate or semi-numerate investors who'll buy into the "no more heatsinks nor fans" spiel.
