I saw ZackG's Aylied ruin's resource and I was inspired to try and place some into my game.
Copied the tex and mesh files into the data files, opened up the CS, but I can't seem to find the model's in the Static tab.
Is there anything else I need to do?

You need to make a new entry in the statics tab and assign the mesh to it (alternatively, you may drag the meshes from windows explorer to the statics tab, it will create the new entries automatically)

* Right click on the static window;
* Pick 'new';
* Enter a name for your new mesh piece;
* Click 'select art file';
* Browse to your mesh folder;
* Select the mesh you would like to add;
* Click 'open';
* Click 'OK'.

You should now be able to select the new mesh from the static window. Do not forget to save your new esp file, as otherwise any changes are lost.

Thank's for the prompt answer guys.
