I am thinking of doing this (putting in an IEC 'kettle lead' socket in the back of my amp), like so:

as I am fed up of the power cable waving about hanging out of the back of my amp and concerned that one day it's going to get caught on something and do some sort of damage. Thought it would be a good idea before cracking out the tools though to check with you smart people on here as to whether there is any reason this is not a good idea, or any issues I should be aware of.
