Space isn't cold the way cold environments are here on earth. The cold we experience on Earth is because we are surrounded by cold gases. Cold wind and cold air will wick heat away from objects. Because space lacks any atmosphere, all thermal transfer in space is radiative. In comparison to convective thermal transfer via air / atmosphere, radiative thermal transfer is abysmally slow, requiring expansive delicate heat sinks which must be carefully aimed and coated to facilitate thermal egress while impeding solar thermal ingress. If you've ever seen a picture of the space station, much of what you may think are solar panels are in fact heat sinks. You can't just stick a server container in orbit and call the job done.
