If you check my post here I made a list of what I would have had to buy if I left the Primo whole compared to what I’d save if I butchered it for parts: Der Froschkönig - Lowrider 3 in Oldenburg, Germany
Obviously, this is highly subjective, because I only had a 3-driver Primo and the LR3 needs 5, so I had to buy a new board, new drivers, screws etc. As you can see, it still cost me quite a bit, but the cost for a new table is also included.
