Product review (4 stars): Haier HBCN05FVS 150-can beverage center evaluation
Make sure to let you unit sit for a day before plugging it in.  This will give the oil a chance to work its way back down to the compressor where it belongs.  The heat dissipation coils on this unit are on the sides.  Having said that keep this area clear for airflow.  I have mine freestanding and can get the internal temperature to get down to 30 degrees.  I have had no problems with the unit except for the following:
1.
  There is a slight amount of dust that I can not clean because it is in between the panes of glass for the door.
2.
  The Wire racks could have been slightly larger gauge wire.
