Thanks gents. After a night with the power off, the same phatom rebooting started within 10 minutes the next day. The used comptuer shop downstairs is on summer holidays, so I swapped the disks, cables & memory in to another chassis I found in the spare room. This has been stable since. Someone suggested looking for swollen/domed capacitors on the main board (Supermicro), nothing out of the ordinary was seen. Onward, Craig.
