Identifying an aluminum panel

[Kyle Owen]

The size is just large enough to fit in a 19" rack. It's also possible that
I don't have what it goes to.

Here are more panels to puzzle over:

In related news, I am missing the bottom panels for an RK05J. Never got it
with the unit I picked up, nor the cards. I've been slowly accumulating
cards, but I'm not quite there yet. It's in otherwise nice shape. Not sure
what happened in its former life.
