Nice side effect of their geothermal energy is that electricity is relatively cheap. I asked a quote, for a full rack in a level 3+ datacenter, using 14 kW (thats their limit) it costs ~1500 euro per month. It could house and power 17 HF Sierra's (@800W) so thats 88 euro per month per sierra, all in. Thats cheaper than many EU and US miners would pay for electricity alone and I havent even tried talking the price down or checking elsewhere. I did check if liquid cooling was a concern, and its not.
$1500 / (14 * 24 * 30 ) = $0.15 per kWh.
Not bad for datacenter but hardly "super cheap". You could use my "datacenter" = garage and get rates 30% lower. Some parts of the US have power rates under $0.05 per kWh.
