Best way to connect a coaxial TV?

Hey, so I'm not looking for any fancy HTPC proper setup yet, as from my understanding that can be quite expensive.

I have an old TV I'd like to hook up as another monitor, but the TV's only input is a coaxial nub.

Possible connections on fiance's computer:
(Newegg.com - ASRock 890GX PRO3 AM3+ AMD 890GX HDMI SATA 6Gb/s USB 3.0 ATX AMD Motherboard)
DVI
VGA
Optical S/PDIF
(HDMI in use)

I'm looking for the most cost-effective way to connect them. Perhaps a converter, cable, or pci card? Audio would be a plus, but not necessary.
Would it even be possible to get both audio and video sent through? Would the Optical S/PDIF do that?

Well they make rf modulators that will turn a s-video into a standard coax signal.
I suppose out there somewhere is one that will do it with dvi.
Or perhaps you could convert to composite and run it through a old vcr or something.

...since the co-axial standards are way below PC display capabilities what would really be the point?

I dunno. Lol, I didn't think it'd be that bad. ^_^"
Just an extra TV that was laying around. No big money for anything of a decent new monitor, but figured this might be worth a few little bucks. Thanks for the input, though. =)

keep in mind it's maximum possible resolution is somewhere around 580x360

He just reminded me of the one all important reason he wants it: to throw Youtube over there so he can maximize everything else that he's working on. So that'll be fine enough.

Would these 2 work? I already have leftover coaxials from the cable guy.

no, those are for audio only.

...and they say such. Probably time for bed for me!
Thanks for the ideas though. =)

using both of the above would probably be the cheapest way to hook up that TV.
I couldn't find a VGA converter that had an RF output, which would have been an all in one solution.

Thanks, I'll check it out tomorrow. =)
