I can assure you. From my massive lot of NuBus cards I'm sure I can find a beastly enough video card.

I do also have the bracket for the floppy drive. I found it rattling around int he case when I found it in a pile of gutted PC's. I should be able to make new SCSI, floppy, and power cables using components that are scattered around our shop.

Sure, PM me and we can discuss mailing that tray. I do also in fact also own a IIx but its power supply seems to be sorta dead unless I was not jump starting the batteries right. It's too new of a system for me to pull parts from I feel.
