I have one for sale. It's a Benq VAD6038 fw: 64930C
It is able to rip XGD2 and XGD3 0800 v3 firmware ready. Almost new drive. Pulled fresh in 09 from a RROD Falcon.
Date stamp is January 2008
can be found on my website.BENq 0800V3
BTW, you don't need a liteon dg16d2s, a benq also works to rip games.
I don't know how you could not open your computer. I've been doing it for ages just opening the side panel. Unless you drill a hole in the side or back of your computer.
