Aurora R4 0YY08V i/o shield. Alternatives or affordable?

I'm refurbishing three Old School Aurora (Predator/ Legacy) with the R4, lga2011 boards -FPV4P.

Budget is blown and I need the backplates. Is there an alternative such as DELL XPS model that may have same mobo layout and usable I/O Shield? I really don't need it to have R4 printed on it Dell support has been fantastic as always ( they have none available through sales) but I doubt that they have access to any of this info.
