Hello,
I would open them up and put the components upside down if you are worried about condensation. If it does form and drip it will be at the top of the components where there are no electronics. I would leave them that way for 24 hours to be safe. Once they get acclimated to the room you can set them up and put in standby. This will slowly warm things up. After a few hours turn it on and leave it on for 24 hours to finish charging up the caps. After all that you should be good. Some of these components can take 200-500 hours. So you will definitely be drying it out. I hope this helps.
