Under command line interface in Ubuntu Server you are not so limited. For example you can see your system's specs by running:
sudo lshw
You can get specific details by using the -C flag to list all you hard disks:
sudo lshw -C disk
It can create an html page with your hardware details:
sudo lshw -Html > your-file-name.html
then open it with firefox:
firefox your-file-name.html
