Yo.
I just put together a Shuttle SB65G2 with a P4C 2.4gHz. It's a pretty black thing.
My first attempt at boot up was like yours: no video.
However, I did not hear a fan running. Clue.
I broke it back down, and plugged the fan into another connector. (I suspect that I had the thing plugged in wrong in the first place.)
It booted up just fine the second go round.
This model has built in WiFi.
The P4C overclocks magnificently.
