Could be anything causing this from your "move" such as damaged ram or 
other component from static or a somewhat flaky power supply in the new case.

Have you run diagnostics on the hard drives?

Make sure all your power connectors are tight, no damaged cables.  It is 
easy with some SCSI cables to damage the cable or connectors, I know I have 
done that a few times.

If you can, separate the power to the hard drives to separate lines from 
the power supply rather than daisy chaining a power line with multiple 
connectors on it.

Have you tried other bootable OS's just to see if they crash too?
