Zoethecus racks

Has anyone ever tried to take a side or front rail off a Zoethecus rack? They are attached with pocket screws; does anyone know if they're glued as well, because that would make it impossible to take the rail off without damaging the unit.
I bought a Zoethecus rack once and some of the front bars had dings where equipment was installed. The bars in the back of the rack were perfect so I switched a couple of them, they were just screwed in, don't remember them being glued. Quite wasy to do just take your time.
Thanks a lot. I'm wanting to take out the bottom shelf so I can slide a fairly enormous amplifier under the rack. This is helpful.
