i need to move alot of files from my pc to amiga, to restore my software.
Have you considered a network connection ?
Or to connect the Amiga HDD to the PC ? Would be much faster than any other solution.
what is my best option to add a cdrom
There are only two CD-ROM drives in your list, so I would take one of them. And as you obviously don't have a SCSI controller, the IDE drives are the only ones you can use.
You should also try the ZIP or JAZ drives. I don't know how they compare speedwise but they are more flexible. You can copy and delete single files instead of the entire CD and you can move files from the Amiga to the PC, too.
