If it vents in the front then you should be fine; minimum to no side clearance needed. Keep in mind most small wine and beverage cooler are free standing and can’t be installed in an enclosure. That should be clearly standard in the manual. As easy check - if the door goes all the way to the floor, then it generally can’t be installed in an enclosure ( no front air circulation vents). That is one of the advantages of Magic Chef. They make under cabinet coolers that are under $500. I got the EFF code issue after 6 years. My install has zero clearance on the sides, 1 inch on top and 4 inches in the back.
