   A 1/4" back isn't going to do very much to prevent sag although it may help a little if it's screwed or stapled to the carcass. It can, however, provide a lot of support against racking.

   Personally, I always put a back in a cabinet with an open front - if just for appearance. Most of the time 1/4" is fine, but I'll go to 1/2" if there are structural issues.

   the 1/4" backer serves to keep the unit square. if you omit that piece just screw a 1x3/4" cleat to the wall and attache your horizontal members onto that

     Hi Velo ,

            The design in the picture shows 3 partition walls in the cabinet . You said a built in , that means the cabinet will be screwed to the walls correct ?

         As long as you support under the partition walls underneath all the way to the floor , I see no where for the sag to happen , you will be fine without a back and once screwed to the wall the back serves little purpose other the visual on some works .

     If this was to be a free standing unit then a back would be a must imo .

            BTW it is a nice looking cabinet , how you gonna make those doors ?

   Thanks to all for the advice

   Dusty:

   Yes, I am going to attach it to the wall along the back and on the right side. 

   I have not yet decided about the doors.  I really like the lattice appearance but my wife seems to prefer frosted glass.  The plans include a very basic procedure on milling the lattice but I have not spent much on it yet.

   Thanks again

    Cheers,

   Velo
