UPC Fan Error Assistance

The CPU fan in my HOG iPC is in need of replacement. Being Friday and a weekend of shows ahead of me I may be in trouble. My PM is checking with some local vendors to see if their repair departments have them in stock. If not, does anyone know of a "plan B" that I can explore?
The fan is 60x60x10 12v/.7w. Would a Radio Shack or Fryes Computer have something that would work?

Any suggestions would be extremely helpful... Thanks.
