Stand Alone with external crystal?

I want to use the internal clock on a pro-mini for power saving reasons (I have already removed leds and reg). Do I need to remove the xtal and capacitors, or can I just leave them there as an option? if I do leave them will I still get the power saving?
Thank you

Do not cross-post. Other thread removed.

If you have changed the fuses to use internal clock, I think you can leave the external components in place with no power change.
