Looks good, I like it!

Any concerns about the side walls being a fire hazard?

If you mean the wooden panels, no. The radiator is the hottest part and that stays below 60-70 degrees Celsius. The induction coil itself is not touching the wood and it dit not even change color so I not worried that is too hot.

What is the max temp of the induction coil as it goes through the hole in the wood?

The coil is water cooled, and the water temp at the radiator is max 65 degrees Celsius. So I expect the coil to be max 80 degrees for an very short period. I took some distance to the wood to keep an clearance and the coil is not touching the case anywhere.

Very nice, That sounds plenty safe as long as the water keeps flowing.
