With most cabinet shops trying to increase profit margins, they simplify the cabinet by eliminate as much of the labor as possible.  They then call it a 'European Style' cabinet, which means they have eliminated the faceframe and use tape or laminate to cover the edge of the sides.  European style has nothing to do with Europe, its just a creative way to make a cost cutting job sound acceptable.  Doing this creates several problems. 

The first is the cabinet is less stable, since the faceframe acts like a skeleton and keeps the sides square and rigid. A cabinet that is out of square will put pressure on the sides and the cabinet will start tearing itself apart at the joints.

 The second problem is the drawers.  Since there is no frame to attach the front of the drawer tracks to, they have to screw them directly into the sides.  Sides are made up of either pressed woods or plywood.  Neither is engineered to hold screws.  The result is drawer tracks that will come loose and eventually fall apart.  The more weight added to the drawer, the sooner it will fail.

 The third problem is similar to the second and is the worst of the three.  The door hinges on a frameless cabinet are screwed into the sides.  Since the weight of the door acts as a lever against the hinges, much like prying a nail with a hammer, the hinges almost always will pull the screws out of the sides and strip the hole or even tear a chunk of the side out with it.  This is one of the most common problems of 'European' style cabinets. 

Here at Unique Woodworking, we always use frame construction (unless the customer insists on frameless for some certain project).  The reason is simple, frames make the cabinet stronger, gives you a stable mount for drawers and doors, and it will last much longer than a frameless cabinet.  European style cabinets will not last, and are not made to last.  I have personally witnessed European style cabinets fail before they are even installed.
