eMachines E730G: Any guides on how to open the notebook to clean cooling fans of dust

Hi, im posting about my stepdads eMachines E730G.
Its been running without a hitch since it was purchased but i noticed its running a little hot.

Since i dont have any issues opening up notebooks i was thinking of cleaning it out and perhaps repaste thermal paste.
But i would like to know more about the notebook before starting, since i dont own it.
I dont mind opening up notebooks that i own myself and the ones i own also have easy access to the fan area of the notebook.

Any help would be appreciated,
