In case anyone is interested in painting their beige drive trays I found the release tabs for the tray today.
To take out the tray:
1. Unscrew the 4 screws on the bottom of the drive
2. Remove the bottom metal shielding and then carefully flip the drive over (the circuit board shouldn't fall out if it's clipped into the tabs)
3. Remove the top metal shielding
4. Remove the fronta face plate if you haven't already done so
5. Push the white piece of plastic at the front in and this will release the drive tray and allow you to slide it out
6. Slide out the drive tray to it's limit
7. Push down the two plastic stalks circled in the picture while at the same time pulling out the drive tray
8. Go and paint it with some vinyl dye and get rid of the ugly beige drive in your Xbox

Hi have you made your drive fit into the Xbox case yet? I'm wondering whats the easiest way before I start hacking up the case unnecessarily, any info or pics would be much appreciated.
