Drilling holes in a fridge, where is safe?

I got an old under counter fridge to use as a 2nd brew fridge with another InkBird unit. Electrolux I think.
The drain looks too narrow to get cables through but I'm nervous to drill. Are there any sides I can safely assume don't contain important stuff... Maybe the top?

Why not drill the drain hole larger?

the side with the switch light etc will have wires horisontaly the back will be busy with refridrent pipes
other than that it's pot luck

Slowly drill through the outer metal/plastic skin then use a skewer or corkscrew to carefully remove the insulation. Hopefully you'll spot any pipes or wires before any damage is done.

If you NEED to drill somewhere other than the door the back of the fridge is out of question. When it comes to the sides it's typically safer in the front half of the side versus the rear half.

I've drilled through the sides of several fridges without any issues - always went for the left side - assuming the fridge light and temp adjustment were on the right.

The outer skin will be thin sheet metal, the inner skin plastic, and a layer of insulation between.

I use forstner bits - meant for wood, but if they're still sharp enough they'll manage the thin sheet metal just fine

I went through the side on a Bosch fridge. Drill just through the metal and then have a prod around through the insulation with a small screwdriver to check you can't feel or see anything important in there before drilling the rest of the way through.
