can't remove power distributor from Supermicro CSE-826 chassis

Nobody responded to my prior request, and Supermicro tech support was no help, claiming that it should work. So I decided to try changing out the power distributor. Mine has no tag, but the new one is a PDB-PT825-S8824.

But, for the life of me, I cannot get the old power distributor out. The manual for the chassis says to remove the 3 screws and lift it out of the chassis, but mine will come up a quarter inch easily and stops. It's not the wires, they're free. Whatever it is, it's some solid metal part in the chassis that interferes with the metal frame of the power distributor.

I thought that by removing the power supply tunnel I would be able to move the distributor back and free it, or at least be able to see what is causing the interference. But I can't get the tunnel out either. I've removed all the screws I can find, the tunnel rattles around like it's free, but won't come out.

Any suggestions would be appreciated.
