Needed small rack for two amps and for drawer to keep cables etc. Self-assembly was easy and contrary to some other reviews, you don't need a drill for attaching the strips. Just need something sharp for small pre-holes for screws, just couple of mm is enough for a pre-hole. I used tape with mild adhesion for marking the position of strips and sharpened screwdriver (big nail for example will do the same) for making pre-holes. I do have a drill, but thought it would not be needed for mdf since you can do more harm than good with that if you are not careful.
