upper case letters in url

I am working on a site that has a lot of dynamically created pages that have uppercase letters in the url.  They are long urls and will probably never be typed in by the user.  I know it is best practice to use all lower case but there are a lot of these pages already out there.  My big question is does it hurt my SEO to have the uppercase letters and should i change them.  
Here is an example.  mysite.com/Article-Satellite-Internet-Now-Available-in-Ragland-AL/01/RAGLAND/12.htm

No,  they are not going to affect SEO and would be a pain to change anyways.

I think at this point, it's more important to worry about the content rather then small things like a caps in the url.  If they were all uppercase, I would worry a little, title case like this, I say you are good.

While on Windows, none of the URL is case sensitive, on Linux only the domain name part is not case sensitive.  Everything after that is case sensitive on Linux because it is part of the file path.

Somewhat related follow up.   I just read with the most recent rolling update, what is in your URL means less and less.  This is a good read about the subject from moz http://moz.com/blog/early-look-at-googles-june-25-algo-update?utm_source=bronto&utm_medium=email&utm_term=Early+Look+at+Google%E2%80%99s+June+25+Algo+Update&utm_content=The+Moz+Top+10&utm_campaign=Moz+Top+10+June+%232+6.27.13
