There shouldn't be any issues, if you let the components get to room temperature before you plug them in. It can be a good idea to unpack everything, so you don't get condensation all over your gear. Just open the antistatic bags, don't take anything out, so any moisture can get out. Most antistatic bags do include a small amount of silica crystals to help with moisture, but they can get overwhelmed.
Be particularly careful with HDDs. They are susceptible to a very quick failure if you start them too cold. I've lost some HDDs to that on vacation in colder climates.
