I am trying to clean the cooling
fan of the power supply. I removed all of the screws
Except the one on the bottom left. Not sure how to get it out.
Can I go any further in cleaning the dust?
You could try something crazy, but it will work.
If you have a vacuum cleaner with one of those narrow nozzles,
you could try to use something like duct tape to tape and hold a plastic straw in the pointed end of that nozzle (leave the rest of the nozzle open to air), then work that straw around to get at the tight corners inside tha power supply.

I already cleaned up everything reachable in the computer.
Thanks for the idea of the straw and the nozzle.
I will use it next time as well with other applications.
Just make sure that straw stays away from any fine jumper wires that are on the Motherboard.

I have no fine jumper wires.
And I have the cheapest Walmart vacumn.
Not a lot of suction.
I am very happy with it.
