[TheGreySpectre]

can someone give me the specs on a 1 unit rack mount, I am trtying to build my own custom case and would like to make the case a little wider and have a rackmount on the side to put things like a switch in but I need the specifications of the mount, holes, dimesions etc.

When in doubt, check a manufacturers page for datasheets and mechanical drawings...
