The mechanisms are no different, but here is what you will need to go through to be able to do it. Is is probably more trouble than it's worth.
- You will need to obtain an external hard drive case
- You will need to obtain a power supply for the external case
- You will need to obtain a different mounting bracket
- You will need to obtain an external SCSI cable and termintor
This is not an easy process, and probably not cost effective when including labor costs.
