The disks are in RAID and verified monthly, I am not afraid of these.
Rather the mainboard from 2005 - bad caps are quite a possibility(*).
But the machine is almost clustered so another can take over its role in
case of failure.
(*) A friend had a IBM Netfinity failure after long uptime and a power
cycle - it asked for POST password that no-one remebered having set.
Official support offered to replace the mainboard (not cheap).
The solution was replcaing bad caps.
