System Specs - When Asked, What Should I Include?

[DOH2006]

This is sort of a general PC question - When someone asks for my system specs, what information should I include? Most of the list would be obvious, but what would constitute a complete system spec for someone trying do evaluate a PC? I have my specs below, is there anything else I should include? Thanks.

If it's for troubleshooting, the voltage on the rails would be good.
The rated output of the psu may also help.

totally depends on the problem really but full details would also include Make and Model of the PSU
Driver versions being used
system temps
manufacturer (or self build)
hell even case would help for some problems
drive layout i.e raid levels, where the pagefile is stored etc
