The only consideration I would have, is if your copper piping is also used for grounding within the building. You could have some voltage leakage which would not be good i.e. interference as you mention. If you have cut it off and there is no water or other liquids in the pipe and it's isolated you should be fine and consider your copper pipe an Ethernet cable conduit. Before you pull the Cat5e through the copper pipe. You might also want to run a pull cleaner (duct brush) through it and see if there is any corrosion. If there is corrosion present, it could could eventually migrate to the jacketing of the Cat5e and eat through your new installation.
The Internet is so big, so powerful and pointless that for some people it is a complete substitute for life.
