Marcy Pro Smith Machine Home Gym System Review - Is It Worth It?

Marcy 3 in 1 Smith Machine Home Gym System with Upper and Lower Dual Cable Crossovers and Adjustable Bench for Full Body Training.
The machine is great. Very sturdy and does exactly what it's supposed to do. The only thing that I guess can't be moved is the bench. The bench is great for everything except the flat chest press. Overall a great machine and one I would recommend.

I see that the barbell is 1 inch in the middle but olympic size where you actually put the weights. Can the olympic size cover be removed? And theoretically use 1 inch hole weights instead on the barbell?
