The issue with those "wine coolers" is that unit is most likely a "thermo electric" unit and they will not get cold enough to safely store foods such as meats, dairy and such.
You need a proper
refrigerator for food storage, not a wine cooler. For food you need a unit that is rated to always be able to store food at below 4 degrees C, which is 40 degrees F. A thermo electric cooler is not rated for that.
