Hi John,
I put one in a 3000 with an SSD. They do work fine, although the Acard ARS-2000SUP I used refused to work with the Warp Engine SCSI, but works awesome on the 3000D (aka 2091) SCSI.
Will need all latest updates of the scsi.device to work well (for large disks that is).
All you will need to do is to replace the loud ps fan for a silent Amiga!
