It's sorta tough for me to make out your exact drive bay situation from your pics. Do you have any open slots under or above your CD/DVD drives? If so, you should be able to install the drive there. If that isn't the case, is there any room inside for you to improvise & attach the drive with some add on brackets, or even wire ties? Or, you could always use the "sloppy" solution & carefully lay the drive on the bottom of your case. Not the best method, I know, but if you really can't install it to an open slot, that would be your only other option.
