user8769: My project is battery powered and it has it's own usb port for charging. Can I snip off the HUGE DC barrel jack which is making it hard for me to fit this into an enclosure.
Or could that cause problems? 

user12003: De sdering would be safer.  You can then use the Vin pin to supply sour voltage (IIRC you can run as high as 12 volts with the uno)

user11754: You can remove it safely without any issues, just make sure that there are no short circuits or any other components damaged while doing so

user313: You'll likely do less damage de-soldering it than trying to snip it off. Use a de-soldering pump to remove as much molten solder as you can, then heat again with de-soldering braid to wick up the remainder. If the jack's solder terminals were bent over (to stabilize the part before it was soldered) you may need to straighten them with a tweezer-nosed plier. Then you should be able to lift the part off the board. Don't overheat the board or heat any other parts or solder joints than those you intend to remove.
