Best HTPC setup

the hd 1600, i dont' believe has directv input.. i have that card, and it has hd input that supports atsc and qam, and an analog input.

UTJ, what kind of memory is that running.. i have some old sticks laying around unused.

fwiw, the xbox360 teamed up with vista home premium, wireless in another room is a much easier proposition.
I played with making a linux one a while back and after fighting with drivers said heck with it.
the htpc case and using liquid cooling would be absolute quiet option as well.. if wanted a standalone instead of front end..
PS3 is def a viable option to with loading linux onto it.
