Considering the precise location ( in Sweden btw, and not just anywhere, in Northern Sweden, close to the Arctic), i presume the outside temperature matters somehow and having constantly low temperatures outside will help with cooling or similar.

Totally uneducated guess, but northern Scandinavia (and Finland) have already been used for datacenters for precisely those temperatures, and if it didn't matter it could be anywhere else with a decent "green" energy mix, like France, southern Sweden, Austria, etc.
