is the location of psu fan important?
i want to build a pc using my old case, the location of the psu is at the back top case, i am afraid that if my psu fan is facing upward, the fan will be covered by the case and disrupted air flow, is it true?

You should face the fan whichever way produces best airflow, so typically fan down in a top mount.
Almost every PSU should be reversible.
to be honest i never build a pc before, my old case come with a power supply in it, when i remove it and try to put it back the screw did not align properly until i reverse it
there are 4 screw, 3 of them are at the corner, while 1 of them is a little bit to the center
