Idoerr, if you get NIC panels, be sure to get the ones with the smaller grid openings. Also, I don't know if you were able to see the smaller NIC cage I posted on the other post, but if you look carefully, you'll see that I overlapped 2 grids to fit on the sides. You could do the same thing to stretch out to the 51" you have. Just use zip ties to connect the grids, rather than the connectors. That way you can overlap to make full use of your space. I hope I'm making sense.
And here's a popular site that explains one way to make a NIC cage:
