I kinda figured I was having an IP address conflict, but never assigned eth0 a

Admittedly I haven't. I try to stick to the saying "If it ain't broke leave it

Yes it it. It's also interesting in other ways, for example, what you said 
above, also made me realize just how meticulous I am.

Now I'm wondering if I suffer from OCD to a certain degree.

Isn't Linux great? :-)
