temp controller in keezer collar?

I'm most likely going to put a collar on my keezer, (magic Chef 7.2) and was wondering if anyone sees the issue with putting the Love temp controller in the collar. SO basically I'd have three taps on one side of the front collar, and then the temp controller on the other end.

I'll be building it in a waterproof box, so I wouldn't get it wet. But does anyone see the problem with the temperature in the freezer being bad for the controller?

Thanks,

its been done...ill have to crawl through the threads later and find it. As far as i know it ende dup fine. The only problem i forsee is condensation...temperature shouldnt be a proble,
