The specifications of both of the rack and the server seem to be on point, but the mounting may be different. It's hard to tell without actually looking at the units or seeing pictures. If you load up some pictures, i'll have a better idea of how close the mounting bracket points are.
Why not just line it up and see if it mounts correctly? It should be pretty easy to see if it fits or not. Or are you looking to buy the rack or do you have it there with you now?
