I'm building a new HTPC system and was going to use a Core2Duo CPU. I want something with no onboard fans, at least 1 firewire port (not essential, can use a PCI card), coaxial (RCA) SPDIF audio output (going into a videocard with an HDMI combiner). Something that will handle a quadcore CPU in the future would be good. Not sure if supporting a 1600Mhz FSB is going to be a future-necessity or not, but I suspect it might be useful for a future QuadCPU upgrade. Doesn't need to handle any more than 4GB RAM.

I don't need SLI, but as well as the 1 PCIe videocard, about the only other card going in there will be a DVB-T Tuner card.

It'll be going into a Silverstone SST-LC17 case which is a full-size case so there will be plenty of room, the CPU fan will be replaced with a high quality ultra-quiet one instead. It'll eventually have a Blu-Ray drive stuck into it probably too once the prices improve.

So, any recommendations for a good board? Something under $400 preferably.
