corsair 900D case REBATE question

[mmuthiah]

I recently send the rebate form for 900d PC case and it got rejected that i didn't send the valid UPC and when i called they told me that i sent the serial number instead of UPC? Can anyone let me know where i can see the UPC for 900D? Bottom, top, left or right side of the 900D box? I believe i checked thoroughly and didn't see it???

 

Thanks for any help, so that i can do the re-submission.

 

Thanks
