OS Version?

I just received my iMac 24 a few days ago. I am coming from PC's and am getting used to this machine. I'd like to check the OS version, but I don't know where to look. Can anyone help?

Apple logo in top left corner, then "About this Mac". Should say "10.5.7" or whatever.

Yup - 10.5.7
Thanks a lot.
