I'm looking to build a box or two and want to use a Linux distribution on it. (That's why I'm asking here instead of in the motherboard forum.) I'll probably make it dual boot just because some applications are M$-only and WINE isn't fully robust yet, at least AFAIK. I know a lot of people are going for the XP board, but since I don't have much interest in XP (let alone in having the majority of a new HD gobbled away by the OS) I figure that board's probably not for me. Or am I wrong?
I'm want to install some sort of voice-recognition software that can be used instead of the mouse. (I'm building the box for someone that has serious dexterity issues, and for whom mousing can be excruciatingly difficult.

) So I will need at least moderate processing speed, I'd imagine. OTOH price is also an issue. I can wait and hunt for sales if need be. I suppose whether I even need to install Windows at all would depend on what software is available for Linux (or a BSD, for that matter). I'll also need to put on music composition software, but I imagine that might be more readily available for Linux.
So I'm looking for both mobo/processor recommendations and software recommendations. The software doesn't have to be freeware, though of course that makes things a lot easier for me.
Many thanks...
