I've already done a search on ebay.Just came across this, maybe it would fit?
Did you ever try to mount a SCSI2SD where the old hard drive used to go?. The holes don't line up. I created a bracket with a standard hard drive footprint so you can mount the SCSI2SD pretty much anywhere that a hard drive would go.www.ebay.com
(First pic is misleading, it's just the bracket.)
