Hi ZeroCoolXbox,
at first I thought that too that maybe I got something like an "Opus 2" just for repairs but then I checked the motherboard with a flashlight through the bottom of the console and compared it to the Zephyr pictures.
I found out that I have three of those wired round spools (positioned flat on the board, not standing up):

The only difference is that mine is made of redish wire instead of a copper like color but that probably doesn't mean anything. So I guess it is a Zephyr after all...

P.S. It came back to me with NXE pre installed
