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.
