well theres a floppy drive model available from sony which doesnt have the fascia so that it could be fit behind the cabinets having floppy fascia. If u have already brought one u can remove the fascia from ur cabinet. I am damn sure it can be done.
Finally u can fix up any of the drives behind ur fascia adjusting the eject buttons one after the other. This arrangement will work good if the eject spring throws ur floppy considerably out.
