I'm re-purposing an old case, but the original system only came with a single fan used for exhaust. Considering that I'll have the psu exhausting air out the back as well, and no other fans, would it be best to leave that fan where it is, as the original manufacturer intended, or remount it to the front (I checked, yes, there is a place for me to put it) for the positive air pressure?
Should only case fan be exhaust or intake?

If you can have a filter, mounting the intake in front behind a filter will keep your case cleaner.
From a cooling point of view, it makes little difference.
The fan on the psu has one job only... to cool the psu.
On an efficient psu of adequate size the psu fan should hardly run at all.
Do not count on such a van for any case cooling.

If you can, mount the second one in front.
Too much exhaust with a strong exit fan will tend to draw in unfiltered air through other openings.
If all or most of your intake is in front and filtered, the hot air will exit wherever and be cleaner.
