I'm not totally clear on what makes something "bodybuilding equipment" vs "S&C equipment". Like, chest-supported rows can be a solid "bodybuilding" exercise. So, I'm a little confused on what you have compared to what you need.
For "bodybuilding", I'd make sure you have plenty of racks, a good pulley system for pulldowns, rows, and crossovers, a good leg press, I prefer a standing leg curl over seated, and something for calves (probably seated). Dead-squat bar for presses, pulls/squats, and walks. I'd opt for a few landmine units so you can do t-bar rows, Meadows rows, and all sorts of presses/squats. Not sure how much room and budget you're working with, so building the dream gym might only go so far.
Hammer Strength DY row. Dorian Yates consulted on the design. He has a big back. That means it builds big backs. (Seriously though, it's an awesome machine.)
