So I got the final go ahead from the wife on replacing our old 19" tube TV with a 24" iMac. I have picked up two Pinnacle 80e tuners and am looking into using EyeTV 3 (hopefully within the frontrow interface if that is possible) to watch unencrypted DigitalQAM. My question is which 24" iMac should I be looking to get. Note any TV shows that we miss by using unencrypted DigtalQAM we hope to be able to get from iTunes.
