I'm thinking about moving my rigs outside of the house, most likely into a shed. I'd be housing around 50 GPUs in there with a view to expand the farm.
Average temps outside:
Month High / Low(°C)
January 7° / 2°
February 7° / 2°
March 10° / 3°
April 13° / 4°
May 16° / 7°
June 19° / 10°
July 21° / 12°
August 21° / 12°
September 18° / 10°
October 14° / 7°
November 10° / 4°
December 7° / 2°

What should I get? Metal or wooden shed? Suggestions are much appreciated.

Those are some nice mild temperatures.
Go with wood, the initial cost is cheaper. I also find them to be sturdier. Also if you are thinking the typical metal shed everybody's dad had in the backyard, they are pretty flimsy after a while and separate at the seams. Lots of insects that way.
Whatever you get paint it white; helps to keep things cooler in the summer sun.
