Remove hard drive on a Compaq Evo D500

[t30power]

Having a hard time figuring out how to swap a damaged HDD with a new one on this mini form factor Compaq EVO D5D case, it seems the case have a tab you press to release the HDD, CD-ROM or Floppy drive, but it seems everything is stuck inside, I can't slide the HDD or the floppy drive. On the second pic there is an identation on the inside of the casing when the device is attached and pressing the green tab at the top makes it flat so that supposedly you can slide it out but I don't know if this is how it's supposed to work.

Here some pics.





Can anyone help me.

On my Compaq C500 SFF, the ODD/HDD/Floppy rotates/flip up, so can you push the button/tab in and see if it lifts up(you might have to push that whole section down first). The Hardware reference guide for the D500 SFF(available on HP support site under manuals) shows that. And it shows that there might either be some kind of level or a tab by the HDD(maybe to the right of the CD-rom or to the right of the HDD) that you pull straight out/move left or right to release it.

Also, on the Power supply unit, there should be a diagram that should give some insight.
