I'm looking for opinion/advice on hanging cabinets on a concrete block wall. I'm making some wall cabinets for my wife's school that will primarily made from 3/4" maple/birch plywood. The will be very large: 40" wide x 24" deep x 36" tall. My concern is will I be able to safely hang them on a concrete block wall. One of them will be in a corner (drywall, metal studs) so I can also anchor into that. I'm afraid of it being very heavy and pulling out, particularly with the 24" depth.

I haven't checked my local big box yet but wanted to know if there is an anchor that will hold these or another method of attaching. There will be a base cabinet under these that I was thinking about putting some kind of post on to help support the upper cabinets or using one complete piece of plywood for the sides of the base and upper cabinet (there will be an 18" space between them).

Appreciate any comments or experiences anyone may have had with this.
