The theft, which took place between late December and early January, is one of the biggest series of robberies Iceland has ever experienced, according to law enforcement.
"This is grand theft on a scale unseen before," said Police Commissioner Olafur Helgi Kjartansson of the southwestern Reykjanes peninsula.There were four different burglaries (three in December and one in January) in total that took place at various locations, two of which went down on the southwestern Reykjanes peninsula.
The thefts, which also included burglary of 600 graphics cards, 100 processors, 100 power supplies, 100 motherboards and 100 sets of computer memory, were captured on CCTV cameras by Advania, the server company reportedly hit by two of the three thefts.

Iceland is home to the data centers of a number of the cryptocurrency mining companies because the mining process is extremely energy-intensive, and renewable energy is cheap there. Almost 100 percent of the power generated in the country comes from renewable sources.
The police are currently tracking high energy consumption areas across Iceland in hopes the thieves will turn the stolen servers on, which could potentially lead them back to the stolen servers' location.
The authorities are also contacting internet service providers (ISPs), electricians and storage units, asking them to report any sudden spike in power usage or other signs the stolen servers had been reconnected.
The police have currently held off from telling the public about the incident for a while, in order not to compromise their investigation.
