Maybe I'm being a bit unfair, but when I fee romex run inside pipe, for no apparent reason, my first thought is "well, let's see what else this homeowner did wrong."
Even if the case is made that this is something allowed by the code, running romex in pipe is a lot of extra work, and a lot of expense, for very little gain.
So, if you want everyone to think "amateur" when they see your work, go ahead. Just quit beating this dead horse, please!
