Wow your HP is similar my Dell Optiplex.
Remove the side cover and slide a couple of latches and tilt the drive cage up and out of the way.
I think you're making a wise decision on staying with a 65 watt processor over the 95 watt processor.
No telling where they cut corners to save cash on manufacturing.
I've only run across Philips head screws for HSF coolers although wouldn't be surprised seeing that star screws replaced them.
We learn as we go through our hardware upgrading usually for the best although I've learned the hard way a few times.
