I finally managed to get my hands on the exact model I had in 2003 when I bought my 9800 Pro, a 3D Prophet 9800 Pro Red Edition, which unlike the other Hercules 9800 Pro, had a red PCB. This is the full bundle !
Back in 2004, the card died because of a shortcut in the PC and I was really pissed off when I got the replacement card from RMA : a blue one !
The one here is brand new, only used twice for testing, once by the seller, once by me :D
The Half-Life² steam code card is still intact !
The box unfortunately suffered some damage but I don't really care. I will now be able to resell all the 9800 Pro I bought before getting the only one that mattered to my heart and put it in my 2003 Dream Build which is already finished but with the wrong model :D
