IDK if this is the right section to post this question but here goes.
If money is not an option what would be the hardware you would use to make a knoppmyth pvr box?
What is the best Tv tuner That I can buy for my nix pvr box?
What processorer should I go with brandwise and model?

Perhaps a search of the forum. These questions have been asked and answered time and again. Avoid ATi.

Money is not an option? Do you meam "money is no object" (i.e - the cost isn't a consideration) or maybe you meant spending money isn't an option (i.e. - what can you build cheap)?

Seriously however, Cecil is right (as he usually is ), this has been discussed ad naseum. Even given how much I enjoy discussing hardware, I'd still recommend that you do some research first. Possibly starting here: http://knoppmythwiki.homelinux.org/index.php?page=PickingComponents
