I know I have a benQ drive, I looked on another guide and saw under the faceplate in a hole, I had white wites, and empty space...

I have 3 xbox's but 1 is a spare, this is the one I will be flashing... It is an elite, and the last 2 numbers of the serial are 07 MFR date is 2007-07-11
Also, for a sata card, do you need to have the nvidia one or the pci sata 6421 something something? I dont think I have a sata card in my computer, I think I have 2 ports on my motherboard (it looks like) I dont really want to buy a sata card, because I will most likely only use it once or twice, and I will have to wait a week to have it installed, because the comp place is slow...
