There is a supplier for rare Mac specific stuff in Japan. He provides a 2.5" sized IDE/SCSI-converter http://www.artmix.com/powermonRX.html to be used piggybacked on a laptop IDE harddisk. The device is designed to extend the life of PowerBooks with internal SCSI drives. The price might settle around USD 130, leaving some space for shipping and import taxes. A 2.5" to 3.5" SCSI adaptor is available, also. This makes up a cute combo with a new silent disk.
