I need some information on Xbox 360 DVD Drives.

Just don't order a Hitachi , make sure you also have the correct tools to flash the drive.

 

But they said that "spoofing" a drive will lead to problems.
Let's say I get a Benq 6038 for the Xbox 360. This may have been the original drive, or it could have been a LiteOn Hitachi.
In this case let's pretend that the original drive was a LiteOn, and I order in the Benq 6038.
If I perform the RGH and then flash the Benq 6038 once I have retrieved the DVD key from the motherboard and put it all back together... what problems can I expect to arise, or will it all run smoothly?

 

I'm almost certain spoofing will cause XGD3 games to no longer function. But don't but a Hitachi, they're completely worthless.

 

So the Xbox I am trying to obtain the key for and give a DVD Drive is a Xenon. I'm not sure if it came with a hard drive but it's white and was made in Australia. Its region code is PAL. Which DVD Drive do you think it could have been? (My search is already narrowed down in the link).
But even then the website said it's not accurate and for reference only, so do I order in a BenQ and just pray for the best?
