Personally I bought unmodded kegs. But to answer your question on behalf of the general population in the spirit of my previous answers:
sometimes people buy them pre-cut, sometimes they do it DIY style.
Just like many things in this world, it's a matter of whether you want to (or have the ability to) do it yourself, or would rather just pay someone else to do it.
