Not at this time. It's difficult to add a button, since the eject button isn't in a consistent location on the drives. It's a bit kludgy, but I think it will be possible to mount the drive such that pressing the front of the top panel will be enough to engage the button. We'll see though.
Worth noting that Silverstone doesn't have an eject button on the FT03/FT03-mini, either.
