some universities or colleges have incentive for lower student price when you contact the it group .
there are some software (Microsoft) discounts, but only valid until you are no longer a student (office is a goo example)
some counties or libraries have programs regarding student trying to acquire computer for school, they are workstations, not gaming desktops. mind you at a reasonable price I would inquire in those places.
another solution would be to buy used as in recycled used certified, I have a number in Houston that sell I5-4570 systems for example Dells desktops for like 250-300.
all depends what your looking for,
