cool, another coffin keezer.. mines mostly built... Very similar set up to your infact.
One word of advice - don't use 2pack epoxy unless you are skilled in it. I did for my glass top and it has set the project back MASSIVELY. It hardened perfectly like glass in some areas and was a sticky mess elsewhere. It's a prick to get off too.
It may stink to high heavens for a short while, but a polyeuro is a much much safer alternative.
Im running the 650ss on mine as well, great piece of kit.
*In relation to the fan, i went to jaycar and got an ultra silent, bearing free long life fan that is damp tolerant. I think it was like 15 bucks. I then have that running to the transformer which also runs my LED strip under the taps.
*In relation to the coffin, you can go to bunnings and get adhesive foam roll. It cost about 40 bucks for way too much, but its perfect for lining the coffin to keep the cold in
One thing i didn't really consider was the joining of my lid to the freezer lid. In the case of your freezer dying, what are your options? Making it as simple to do a "swap over" as possible, would be great foresight.
i need to update my thread -

I'm no cabinet maker ( i am a sparky tho) , but I've learnt a lot building mine so if you have any questions, ask away.
Can't wait to see it finished.
