The baseboard is against the wall. I can't totally but the cabinet up to the wall because it hits the baseboard before the wall. I was thinking of trimming out the bottom or the cabinet but 1. I don't think I could do it and 2. It has a wood bracing piece all the way along the bottom. Can I mount a piece of wood to the wall to "shim" out the area and then screw it to the wall? Also, since we're on the subject my other two cabinets are not attached to the floor (no walls where they are). How do I go about doing that?
