Well, cablecard solutions do exist for Kodi.
Dunno if they would work with your existing hardware.

I kinda lost interest in cablecard over the years, starting with my Philips component video input DVD recorder, the Hauppauge HD capture boards, and more recently Hulu and Netflix. I have the XBOX extender kit still lying around but these days my viewing habits rely very little on cable. I'm keeping an eye on Dish's Sling TV. If they add a few of the right channels in standalone packages I might switch to them. Or whoever lets me ala carte the five channels I watch often enough to justify the cost.

If your primary use for that PC is as an MCE box then upgrading is definitely not a good idea.
