Interesting, can you elaborate on the method?

Feel free to use mine,

IPX, Sticker: SBZ9, MAC: 8:0:20:0D:AE:2C (Might be 8:0:20:19:F7:47 
instead), Host ID: 5721b630,

These are extracted from the logs from it's original hard drive (as far 
as I am aware, I am not the original owner, so it may have been changed)

Thanks,
Ethan
