I’ve had terrible luck with under-counter beverage fridges. So expensive to buy and and lots of repairs. My repair guy says this is pretty typical for all the brands (so it’s not just my Marvel) and to make sure to buy an extended warranty. He suggests any middle of the road brand (Frigidaire, GE, etc) as the pricier brands aren’t more reliable and the repairs/parts are more costly. If you are still in design phase, can you work a second regular size fridge in anywhere to serve this function?

I've had a Sub Zero beverage fridge for 7 years now with no issues. It's used daily.

we have two liebherr beverage fridges - one indoor and one outdoor unit. silent - no issues so far - 5 1/2 years in. Don’t worry about the stainless - it will blend and many indoor units have glass on the front with minimal stainless.

We have a Danby under counter and it has been great. while not cheap, it was a cheaper model than many others. I rarely hear it and it cools my craft beer quite well.
