I think thats exactly whats happening max... this is really just
"Max Builds a Gaming PC With Maybe A TVTuner"I've got a few questions - do you expect to be encoding 24/7? If not, the increased power usage, cost and thermal output of the Core i7/Quad cores are all far in excess of what you need for HTPC "duties" (if you want to throw in gaming, sure...a faster CPU may be better, but those are going to somewhat extreme lengths)
Why use a HTPC case? If you want low noise AND the most high end graphics (last thread saw people wanting 4870x2!), a larger tower case is the way to go. A HTPC case is great for when you want to stick it in a cabinet, but with the amount of heat these sort of components are going to create, it'll combust!
Even with integrated graphics my Intel Pentium Dual Core E2160 @ 1.8ghz (rebranded Core2Duo chip with less cache) handles Bluray movies at 1080p, all while running under 100w.
Whats the bet somebody suggests 4-8gb of ram for when you get up to that section?

edit: oh, bonus question, the two inputs would be 0 and 0
