External Chassis Fan

Does anyone know of a trusted place I can find a 90/92mm case fan that will sit on the outside of a chassis? Looking for something funky with lights and not just a plain black one.
Thw reason is because my new chassis came with a fan on the top, but inside the chassis of course. The power supply I got prevents the fan from being use within the chassis. So I am looking for an alternative to this.
Thanks.
