No one will probably notice other than your roommate. It's advisable to find out what your roommate is bringing. Two people can share one frig. Depending on which hall you are assigned to, two mini frig's may not fit or will make it VERY tight. There is also a community refrigerator to store larger stuff if needed.
Some students rent the mini-frig/microwave combination and split the expense. This is the only microwave allowed in the room. It saves having to haul the thing in and out unless you think you are going to need it after your freshman year.
