It’s not very easy to do as you have to extend the pins on the Pi GPIO and POE connectors with headers and then hope the fan etc does not touch the screen. Have a look here
for an example - you may want to add another set of headers to give room for the fan to pull air and avoid any contact with the display
You may want to have a look at this
as an option.
Need Pi spray - these things are breeding in my house...
