You can't really define an HTPC though. Lets bitstorm define what it is to him.
Thanks & that's how I feel. I want to run the more-processor intensive stuff like MAME and be able to encode high def as fast as possible, and still have some headroom.
Yes, a lower end Dual Core or even mid-range Pentium IV would be adequate for MOST HTPC needs while using the smaller enclosures. I like those, but I'm really going after power and because of the heat/limited space I am more interested in the type of box that allows for a little elbow room and looks more like a stereo receiver.
My main HTPC is simply an HP with media center and an HDMI cable for the TV. It's not trendy, all it is is a computer setup next to a TV, but it works...
