Ok, I won't tell her....how much are you paying to keep my mouth shut?
Yes, I'll be experimenting with the esky idea & the other idea you had Lester about just bunging the unit on the back.
If your idea works it'll be the best thing since sliced bread! No holes etc. It's also more like 'active cooling' than the esky. Perhaps a combo of the 2 ideas may work too....food for thought until I receive the peltier.
