View machine details and metrics for deleted machine

We have a need to lookup the specs on a system which has since been deleted from our simplehelp inventory. We can see the session history from the logs, but we can only pull up the machine and host name. Is it possible to access any other information about the machine now that it’s been deleted? We’d love to know the make/model or even serial of the unit.

The only way I know is the History tab.
You should be able to click the session and see hardware details at the bottom SN included.

If for some reason it does not, maybe and old simplehelp backup would have it?
