I always use some automotive vacuum line sliced down one side around the hole to give a nice clean finish and protect the wires from shorting.
I went to a DIY store today i could find and hole saws only the ones for wood and the biggest size i could also find was about 70 max. Are you sure there are no other ways to do this dosnt have to be a neat hole but clean would be nice. (I'm trying to cut a hole under the Antec Nine Hundred for the PSU fan).

Thanks.
